AMD's Latest AGESA Update Removes PCIe 4.0 Support from Pre-X570 Motherboards
AMD's latest AGESA update, which is being seeded to motherboard manufacturers, culls efforts to implement support for PCIe 4.0 in boards not carrying the latest X570 chipset. Some motherboard manufacturers had enabled support for the new standard on existing B450 and X470 motherboards - some with limited support, as was the case on some of ASUS' motherboards, others with full support. However, these efforts from motherboard manufacturers went against AMD's strategy with their X570 platform - all in all, these "rogue additions" reduced one additional feature of new X570 motherboards over their older counterparts.
The new AGESA code carries the part number AM4 1.0.0.3 ABB, and will likely be reflected in manufacturers' release notes for new BIOS versions that incorporate the code - and remove added PCIe 4.0 functionality. Other changes in this AGESA code release include fixes for Destiny 2 gamers' woes, which were having a hard time getting the game to run properly on Ryzen 3000 processors. If you're an avid Destiny 2 player and want PCIe 4.0 support, you'll likely be reminded of Rick and Morty's pickle episode. If not, you can always defer these AM4 1.0.0.3 ABB updates, if your system is behaving properly.

Perhaps some glue may help your problem
Im afraid the only one taking money driven decisions here is AMD !
Also, $35 difference is like 20% cost difference between bottom dwellers. The difference in Z370 to Z390 currently on newegg (US) is $6. If you compare Z370 to Z390 the same board, the difference is $1 (Asus Z370-P and Z390-P not counting for sales, just MSRP).
Its more bandwidth amd lower voltage... like DDR3 to 4... wont make a difference really as most things arent bandwidth starved in the first place.
to build a bridge and get over it
It is what it is folks AMD don't want x470 or lower to have PCIe4.0 so just deal with it if can't then don't update your BIOS but be warned if shit hits the fan blame your mobo manufacturer not AMD
