From my 3 network devices in proxmox enx4865ee16751d is never active. I'm not sure how can i debug this.

I need them to be able to bridge them for a pfSense install

cat /etc/network/interfaces

auto lo
iface lo inet loopback

iface enp1s0 inet manual

iface enp2s0 inet manual

auto enx4865ee16751d

Hi,
are you sure an interface with that name actually exists? Do you see any mention of the interface name (or errors related to the NIC) in the system journal during boot? What does ls -l /sys/class/net show?
