I should have mentioned that the screen blank flashes or flickering, is not the only symptom since there it comes with very little but noticeable "adjustments" of the screen brightness, and then, from time to time, the blinks. This all occurs specially when the PC is being used or working, seems less frequent at idle.

I noticed I don't have this problem on Linux Mint, and I also noticed that going back to Kernel 5.8 on either Ubuntu 21.04 or 20.04.2 this problem stops. I have been using Mainline ( https://github.com/bkw777/mainline ) to install previous kernels (5.8 and 5.4 wok just fine, but anything above this problem comes again). Thanks so much beforehand.
