Hello
new HP Elite 600 G9 TWR series computer with new PCI Gen4,
is it possible to change the transfer of the PCI slopt to work as PCI Gen3?
The computer does not recognize PCI cards that work in Gen3 slots, the system does not see the card at all
The card works fine on the previous generation computer that had PCI Gen3
I note that the service manual says about changing the transfer, but the BIOS does not have such a function

What card are you having problem with.
You have 3 gen3 slots and one gen4. The gen 4 is slot #24 in picture
Some UEFI bios it is possible to set the gen to "default" ,"gen1", etc
look under advanced.
The latest bios is 2.03.01 dated May, 2022
https://support.hp.com/us-en/drivers/selfservice/hp-elite-tower-600-g9-desktop-pc/2100963609
windows 10 and 21h1
Possible an adapter might not function in a gen4 slot even if the slot is backwards compatible.
In addition some boards may work in one slot and not in another due to resource allociation.
Are all 4 PCIe slots filled?

Looks like that feature is limited to desktop workstations
If in bios it would be in advanced -> chipset or options
What card(s) is the problem?
If you have an incompatible graphics card it could go in slot #22
or even in any of the x1 slots as long as the back of the socket was open

You may have a conflict with existing USBC
I tried two high speed USB3+C multilane cards in an Area51 that already had USBC and neither of them worked.
They worked fine on workstations that had no USB3
The symptom I had was the board was recognized but always had an error icon
I suggest you add a powered USBC port expansion on the existing USBC on your front port
