Raspberry Pi as TCP Hub/VESC Express

Hello

I have a Raspberry Pi with a CAN interface connected to VESC 6.
Is there any way I can have that Raspberry Pi show up in VESC tool, and than use the Raspberry Pi as a bridge to configure the VESC?
I.e. more or less the same way a VESC Express would work.

And here some information from Raspberry Pi:

ubuntu@ubuntu:~$ for iface in eth0 can0 wlan0; do ip addr show "$iface"; done

Where 0C is a VESC on the CAN bus with ID 12.
