I have a B450 Tomahawk Max (Arsenal Gaming) Updated the bios, but after update there's no prompt message or something
(the lastest bios update -) then proceeds to restart, after that Splash screen and bios dont show up in any video ports of my graphics card
but proceeds to boot windows 10. the screen just say "No Signal" then boots up, if tried to access bios by Del key it says the "No signal" then goes to stand by mode
i had to press the restart button to just go in the boot windows again. I've tried reset the CMOS by removing the Batt and by Shorting by CMOS Jumper. I can still play games with it but i'm just worried about this event.

Setup:
-Amd Ryzen 5 3600x|
- MSI B450 Tomahawk Max "Arsenal Gaming"
- Sapphire rx580 8gb
- Mag241c MSI Monitor
- Hyperx RGB 16GB(8x2) Ram

A lot of the RX 500-series graphics card models are known not to have a so-called GOP and properly signed firmware, which causes problems with the BIOS in pure UEFI mode (due to Secure Boot being enabled by default now). See my post here and follow the links.

You can have all sorts of weird effects when trying to use an older graphics card with this newest BIOS that has Secure Boot enabled. The most common one being a blank screen when you are trying to enter the BIOS and/or a blank screen until Windows is loaded, or not even getting a picture. To fix this, you either need to update the graphics card's BIOS/firmware with one that has a GOP, or you can try to borrow a newer card (2019 or newer will pretty much guarantee that it plays nice with the new BIOS), enter the BIOS and disable Secure Boot, and try again with your RX 580. Or if that fails, downgrade the BIOS to the one before this (still using the newer graphics card, obviously). Then you will be able to see the BIOS again. The third option is to outright buy a new graphics card altogether, then it would all work properly again as well.

There seems to be a very well-known, longtime problem with the BIOS or POST not showing when booting with the monitor attached to a DisplayPort cable. Nobody seems to be interested in solving that problem, the very few fixes I could find did not work for me. I ended up using an HDMI cable, perhaps you can try that as well.
