I have just upgraded a PC to an ASUS B650M-A AX II motherboard. The PC runs Windows 11 Pro and is used specifically as a NAS/Plex server, so ideally should be headless since I can access it remotely from my normal desktop computer.

My questions is: how can I get the system to not constantly flash an error code on the case light when a keyboard, mouse, and monitor are not attached?

Full system hardware configuration is as follows:
CPU: AMD Ryzen 5 7600X
Motherboard: ASUS PRIME B650M-A AX II
System Memory: G.Skill Flare X5
Video Card: NVIDIA GeForce GTX 1050 Ti
Case: Nanoxia Deep Silence 3
Power Supply: Corsair RM750
