VyOS doesn't support other modes rather than default Nx40G out-of-box with 40G Intel NICs due to licensing limitations. You can download an additional package from the official Intel website and change NIC operating mode manually. Here is an example on how to do that:

Download the required package for Linux on your VyOS device

wget https://downloadmirror.intel.com/25851/eng/Linux_x64.zip

Unpack the downloaded archive, enter the unpacked directory and make qcu64e file executable

unzip Linux_x64.zip 
cd Linux_x64 
chmod +x qcu64e

Check available devices

sudo ./qcu64e /DEVICES

Check available modes

sudo ./qcu64e /NIC=1 /INFO

Set NIC mode to 4x10G (device reboot required to finish NIC mode update)

sudo ./qcu64e /NIC=1 /SET=4x10

Check NIC info and mode after reboot

sudo ./qcu64e /NIC=1 /INFO
