I do not have this HW either but from a quick look you need to do two

# apt install pve-headers
(the script assumes that this is linux-headers-*, and thus fails here already)

Open the "install.pl" file in an editor and search for the "sub uninstall"
There add an early return:

return 0;

immediately after the opening { after that you should be able to build it.

It tries to install it directly with dpkg and that may fail, if so try to
install it manually with `apt install /path/to/package.deb ...other.deb`
you may want to pass all debs from the DEBS sub directories to that one
