Question B550M-A bios settings for smoother gaming?

Hi,
I'm relatively new to learning Bios optimization. Just wondering if anyone has any Bios setting recommendations for a more consistent/smooth gaming experience?

Specs

Gigabyte 9070 XT OC
Ryzen 7 5700X3D
ASUS Prime B550M-A WIFI II Micro ATX
32g Corsair 3600 DDR4
850W Gold PSU
OS 1TB Kingston Fury Renegade 6000MTs/7300MTs
Main 180Hz 0.5ms 1440p AOC DP 2.1
Second 155Hz 1ms 1440p AOC DP 1.4
BOTH RUNNING AT 120Hz in settings
Fast Internet via Fibre Ethernet Cat6 Cable
Vader 4 Pro up to 1000Hz I only use 250Hz or 500Hz max (wired)

What I've changed that seems to help:
Disabled power down enable and any other power saving settings that I could see
Set Infinity Fabric Clock to 1800mh
Turned off fast boot
Disabled Security Device Support (fTPM)
Made sure RAM is running at 3600Mt/s
Made sure Re-Size Bar is Enabled

I'm not looking for the best fps possible, just a more consistent/smooth gaming experience and I'm very newbie when it comes to bios settings so if anyone has any recommendations for bios settings that may improve system stability or help reduce momentary game freezes/stutters it would be much appreciated.

Stay blessed

850W Gold PSU
850W is the advertised wattage of the PSU while Gold is the advertised 80+ efficiency rating for the unit. What is the make and model of the unit? Age of the unit?

If you've performed a GPU upgrade to the RX 9070 XT, did you run DDU to remove all GPU drivers(intel, Nvidia and AMD) in Safe Mode, to later install the latest GPU driver sourced from AMD's support site in an elevated command, i.e, Right click installer>Run as Administrator?

Turned off fast boot
This should be turned on.

Disabled Security Device Support (fTPM)
As well as this.

Set Infinity Fabric Clock to 1800mh
You merely need to make sure you're on the latest BIOS version for your motherboard and you enable X.M.P/D.O.C.P in BIOS. You don't need to manually set the infinity fabric clocks in BIOS, not unless you're having stability issues. On that note, what BIOS version are you currently on for your motherboard?

Speaking of stability,

got a link to this ram kit?

It was a pre built system from AWD.IT And I did run a clean DDU reinstall just in case. I'm on the latest bios version but when I tried to install Mobo drivers it only let me install 1 or 2 of the drivers and the others said "operating system doesn't support this application" when trying to install. With the Infinity Fabric Clock someone in these forums recommended setting it to 1800mh for best stability and I read some other things online with fTPM causing stuttering issues. Ran a bunch of stress tests and all seemed good with no errors detected from what I could see. But when playing games performance is really inconsistent. Sometimes when I boot up a game it'll run great for my standards with roughly 110fps avg (FPS capped in MSI to 110) and 1%lows of roughly 70-100fps avg which feels pretty smooth for me for the most part but my game seems to freeze in certain scenarios for example opening my inventory in DayZ not every time but 1 out of every 4 times I open my inventory the game will freeze completely for half a second or so and sometimes it just happens randomly without opening my inventory not super often but even when not in demanding scenes still occurs. Also something I noticed when I restart the game or my PC and load back into the same server, same graphic scene, same AMD settings, same everything. The 1%lowfps seems to be significantly worse constantly jumping from 50-100fps and the random game freezes from opening my inventory or whatever seem to be more frequent and feel worse. It's really strange and my brain can't quite understand it but it's like I load into a game fps feels pretty smooth, I restart the game or the PC, load into the same game and it feels significantly worse and vise versa. Which led me to believe either the drivers are far from optimized for the 9070XT as of yet. Or my bios settings ect aren't set to the best options.

My CPU doesn't seem to be bottlenecked only sitting at around 25-35% utilization roughly 60°c whilst gaming with some cores hitting 75-90% utilization and my GPU seems to comfortably sit at roughly 60°c aswell whilst gaming
