Just create it, it's not there by default but gets considered by
pveproxy - if there. And pveproxy resides in the pve-manager package

Not all our packages begin with pve, e.g. qemu-server, novnc-pve, etc.

Use `pveversion -v` to get a list of all packages directly relevant to
PVE and it's version quickly, can also be found in the Web UI (Node ->
Summary -> Package versions)

cheers,
Thomas
