Had a very similar issue with my ASUS TUF 4090 (non-oc) + ASUS x670e Hero + AMD 7900x in the below ROG forum thread. I tried many things and i did not manage to solve it. But perhaps anything in the thread below can guide you? Check it out.

Hello guys,
I turn to you with the request for help, because I have no idea what else I can do. I can't get my TUF 4090 OC to run on the 670e Hero.
The Hero has BIOS 0805, the card is not recognized at boot, the screen stays black. Except RAM on EXPO 1 I have no OC settings enabled in BIOS, it's all default. The error codes of the Hero do not give a consistent picture. Sometimes it boots into Windows on the iGPU, sometimes not.
Two times I managed to get into Windows with the TUF 4090, at the next restart again the same picture - then it didn't work anymore. This on different Hero BIOS versions.
The TUF 4090 runs without problems in my old system. Is immediately recognized and boots. My old RTX 2080 runs without problems in the new system. So it must be the combination of the TUF 4090 with the Hero.
Even with CMS enabled nothing changes, PCIe 1 is on force 16. The TUF 4090 has the original vBios. I have done several CMOS RESETS as well. No change.
*The specifications of the new system: X670E HERO (BIOS 0805), AMD Ryzen 9 7950x, Corsair Dominator 64 GB (EXPO 1), GPU ASUS TUG Gaming 4090 OC, bequiet dark power 1200 W.
*Do you have any ideas ?

How are you Powering the card?
Are you using the adaptor supplied by Asus, an adaptor supplied by "Be Quiet" or even a third party cable from the likes of cablemod that connects direct to the PSU at one and and the 12vhpwr on the other? This can be critical because if the card doesn't think it is getting at least 450w of power, it wont boot. Now i realise that it is sort of booting sometimes but it could still be down to a power fault.
What about the Power connections on the Motherboard?
Presumably you will have the ATX 24pin cable connected, but did you connect both of the EPS 8pin connectors to the left and above the CPU socket, or just one? in theory it shouldn't matter if at least one of these is connected, but i always err on the side of caution and connect both anyway.
Have you tried any other BIOS versions?
0805 is a Test Bios as far as i know and isn't exactly supported as a traditional BIOS would be, or perhaps its better to say that a test BIOS is way more likely to cause problems and it is not unreasonably to assume that might be the case here. If you haven't already tried, I would suggest going back to the last official BIOS which is 0705 and seeing what happens there.
Did you do a Clear CMOS after flashing the BIOS?
Some people recommend this, i have done it myself, but its maybe a good idea to ensure the slate is cleaned before trying again. I know you have said you ahve no Overclock in place, but what happens if you do a clear CMOS and change nothing in BIOS? not even enabling EXPO etc...
