Setting up a ROG Rapture GT-BE98 on BeFibre?

As background, I presently have two ZenWiFi AX and one RT-AC5300in a mesh network. The ZenWiFi AX has never connected correctly as my provider (BeFibre) requires DHCP connection and VLAN tagged 10, which the ZenWiFi AX does not support (a red light is on but the internet works OK apart from not being able to use some functions on the router such as automatically updating firmware).

I have a new router (ROG Rapture GT-BE98) and during the setup process have selected DHCP, however, I could not figure out where I set up VLAN tagged 10? Where do I set this up?

The ROG Rapture GT-BE98 is working without setting up VLAN tagged 10, but upload speeds are much slower than with my ZenWiFi AX, is this because I have not set up VLAN tagged 10, and are there any other settings (apart from VLAN tagged 10) that I need to consider?

Thanks in advance.

wan tagging is on the wan page and the 802.1Q section

Thanks. I am in the WAN page and can not see tagging in any of the tabs? The manual does not have reference to 802.1Q or tagging. Can you provide a bit more detail? Thanks.

this is from the GT-AX11000 stock firmware but should be there on the be98 (didn't want to give the merlin firmware image link because of the fact that it may be on a different page)
