How many port-based VLANs?

According to a previously given answer, the internal managed switch is able to assign one 1Gbps lane to a specific port, but can we assign as many vlans (non-tagged) to ports as we want?
The goal is to be able to use non-managed switch to group devices
TV, Console, tablet -> vlan4 -> port 1
Office -> vlan5 -> port2
Lab -> vlan6 -> port3
etc.

Looking at this doc, it seems we’re not limited: https://www.turris.cz/doc/navody/nastaveni_vlan
1-5 HW ports are linked to a VLAN and that VLAN is linked to either eth0 or eth1.

(BTW, the diagram in the Omnia is the same as in the original Turris, so it will work the same)
