AXC F 2000 EA: IEC 61850 goose... no VLAN support?

Hello. Managed to create IEC61850 GOOSE messages, unfortunately there is NO VLAN support and the ethernet packets are generated as UNTAGGED.
The protocol conformance doc for PLCNEXT “IEC61850_PICS” claims support for “generic substation event (GSE)”. This should include VLAN support.
Any Idea on how to handle VLAN?
Thanks!
