SG-1100 How to link/merge a VLAN to the OPT port?

[Cabledude]

Hey all,
I have an SG-1100 configured with VLANs tagged out from the LAN port, which is a quite common config.
For the sake of this topic I have:

• VLAN10 for secure devices
• VLAN20 for IoT devices
  See figure 1.
  The current switch port config is in figure 2.

My question is: I would like to use the hardware OPT port as untagged VLAN10 to connect devices such as laptops.

Basically my question is how would I be able to link VLAN10 to OPT so that wherever I plug in my laptop either the OPT port or port 13 on the UniFi switch, it gets connected to VLAN10.

How would I configure the switch ports and and switch VLANs? Or would this be done by bridging?

Thanks, Pete
