No.

I wouldn't completely say "No". ASUS has a utility you can use to stage a BIOS update through Windows (https://www.asus.com/support/FAQ/1008276/) and Gigabyte has a similar utility called @ BIOS that, as far as I can tell with socket AM4 (I don't feel like looking at other platforms), it's still available.

So conceivably someone can with remote tools stage a BIOS update. But the computer still has to restart, which if that happens the remote connection gets lost so I don't know how useful that'll be for a malicious actor.

the OP already bricked the bios. can't boot

I interpreted the question as "could someone have remotely updated my BIOS without me knowing?"

Or:
"My friend needs his BIOS unbricked, but doesn't know how. Can I do it remotely?"

Either way....No.

I would not say no anymore. I have a dell that gets bios updates via windows update.

I have a Lenovo laptop that does this.

Significantly different than someone 'out there' reaching in to your system and updating or bricking it.

I don't want to update but flash via ch341a because I have a brick

 

[rgd1101]

take it to a shop.

That would require a ch341a type device that can be operated remotely.

i has ch341a

It's the "can be operated remotely" part that you're missing.

For what it's worth: there's really no demand for something like that since connecting it to the BIOS chip requires a physical presence anyway. The best you'll do is get someone to talk you through doing it.

I can but... I think you should do it by yourself.. I used CH341A to program And fix Motherboards, Code Arduino, STM32F103, and ESP8266 a lot of times... It's very handy thing to have.. and you can flash Bios easily with it..
