Apart from what is stated in the comments, as far as I understand your question, I can offer a solution to try - if necessary - until the question is clear.
During the development of Windows,
We know that "Windows Vista" drivers are available in "Windows 7-8". In my research on "can you use Win 10 drivers with Windows 11" on Google, I came across headlines confirming this.
In this context, my suggestion is:
Install windows 10 on your device, hopefully without having to activate it. After installing the necessary drivers - or after downloading the drivers with windows update (I'm not sure if this part requires activation) -,
Drivers on the system you installed
dism /online /export-driver/destination:<path>
Export it to an external disk with the command,
After installing Windows 11, all ! For marked devices, install it by pointing to the external disk directory you selected in the previous step, by saying browse for folders.
Ps. I don't know if there is a legal requirement to state that Windows is a commercial product of Microsoft Corporation.
