[PVE-User] migration from iptables to nftables

[nada]

hi folks
I am testing migration of firewall from iptables to nftables
my versions
* pve-manager/7.4-16/0f39f621 (running kernel: 5.15.108-1-pve)
* iptables 1.8.7-1
* nftables 0.9.8-3.1+deb11u1

# nft -V
nftables v0.9.8 (E.D.S.)
   cli:		editline
   json:		yes
   minigmp:	no
   libxtables:	yes

I've already translated rulesets from iptables to nftables
and want to deploy them at pve-firewall

PLS can anybody let me know the configuration of pve-firewall.service 
for nft ?
current for iptables

# cat /lib/systemd/system/pve-firewall.service
