Change Source Ip- Remote Radius

Hello Community, i have a question about how the Radius service in peplink connect to the Radius Server.
We have a MAX-HD4 with 8.1 firmware, we add a Remote Radius Server, the query to the radius server is sent from the SOURCE IP of the VLAN 1 (untagged/none), the question is, there is some option to change this SOURCE IP to another IP/Vlan that was created in the HD4?
For example:
vlan 1 192.168.1.1 (the request is sent from this ip)
i need to change the request to the remote radius server from the
vlan 2 192.168.2.1
i can’t find an option to do this.
Always the request is from the vlan 1?

regards.
