A1707 820-00281 OS problem

[Djsp]

I have this card that works perfectly the only thing that in the Monterey installation once you enter the password, it tells me that it can't install an update and doesn't keep me

Is propably better to keep previous macOS version.
Just in case, check if accepts Ventura.

I did a test with an external drive with high Sierra installed and it did the same thing, it just goes into safe mode

Corrupt bios?

Try known good BIOS.
Failure in macOS upgrade caused problems many times.

I try to do a restore in dfu mode, if I possibly want to replace u4200 I can use a 820-00928 donor, I'm afraid that part is affected by corrosion

Not sure, nobody mentioned such change before.
