Connectx-4 Mellanox MCX4421A-ACQN Opnsense not working

[unnammed111]

I got new hardware, and I haven't been able to get my opnsense to detect Mellanox MCX4421A-ACQN.

• I tried to add mlx5en_load="YES" but It did not work.
  I restarted multiple times with no luck
  dmesg | grep mlx via CLI... nothing happens

I really need help please.
