Code:
# the PVE managed interfaces into external files!

auto lo
iface lo inet loopback

iface enp6s0f0 inet manual
mtu 9000
iface enp6s0f1 inet manual

iface enp132s0f0 inet manual

iface enp132s0f1 inet manual

auto vmbr0
iface vmbr0 inet static
        address  192.168.100.22
        netmask  255.255.255.0
        bridge-ports enp6s0f0
        bridge-stp off
        bridge-fd 0
        mtu 9000
 
Remove mtu value from your raw interface.
Check with 'ip a' what interfaces has Jumbo Frames.

Your switch is already configured?
