The more expensive boards are more complicated and none were designed for this. The simple boards don't have as much going on so they may be able to be tweaked more easily.
Also there may be a matter of validation. Due to the complexity of the high end boards ASUS may not feel comfortable enabling something that may cause unforeseen issues.
Practically speaking nobody needs this anyway. No GPU needs it and any SSD won't perform noticeably different. Perhaps in a year or two it will matter but by then these boards will be well outdated.

With all due respect this is total nonsense ! What complexity are you talking about ?

Just speculation, but given those boards are more complex/crowded I'm wondering if the traces are not as simple as the ones on the simpler boards. Also, even high quality traces could receive interference if there are other traces crowded nearby.
I could be wrong but there has to be a reason ASUS chose some boards as OK and some not.

I'm wondering if it's smoke and mirrors, when I updated the BIOS on my B450-F it says Gen1,Gen2,Gen3 and Gen4 in the PCie 16 drop down. I ordered a 5700 XT and will try the GEN4 option when I get it. Also, ASUS did a BIOS update in May in advance of the 3000 series proccessors, if it doesn't work with the new update I'm going to flash back and see if the original update has it enabled, it came out well before AMD pulled the support. But then again I just got into this a few years ago, I'm just guessing.

So your B450-F gives you a Gen 4 option with the latest BIOS if i understand you correctly ? If true that's a good thing because according to this list B450-F shouldn't get PCIe 4.0 so it would mean that this is only a preliminary list .
By the way you don't need a PCIe 4.0 GPU to test that you can enable PCIe 4.0 even when using a PCIe 3.0 GPU ( you won't see any difference between PCIe 4.0 and PCIe 3.0 anyways especialy not with something like a 5700XT but yeah thats another topic ) .
