If you mean for containers, you can add `lxc.prlimit.*` entries to
the container's /etc/pve/lxc/$vmid.conf file. This is currently not
exposed via the GUI or pve-specific keys (yet).
Eg. in /etc/pve/lxc/401.conf you could add:
lxc.prlimit.nofile: 1337

The resource name is just a lower case version of what you see
when running `prlimit`.
Note that this only makes sense for unprivileged containers, as
privileged containers (unless the capability gets dropped in the
config) can usually override those limits anyway.

If you meant something else, the usual debian/systemd/... ways apply
(eg /etc/security/limits.conf and LimitNOFILE etc. in systemd service
files (see systemd.exec)...)
