Can the guest access be used with routers from other manufacturers?

The guest access of the FRITZ!Repeater can only be used with a FRITZ!Box.

In the FRITZ!Mesh, the FRITZ!Repeater expands the guest network of the FRITZ!Box by making a further Wi-Fi network with the the FRITZ!Box settings available. The guest access cannot be used with routers from other manufacturers.

If your router has its own guest access function, you can use the FRITZ!Repeater to increase the range of that guest network. To do so, connect the FRITZ!Repeater with the router's guest network. Note that in this case, the FRITZ!Repeater only expands the router's guest network and not the router's conventional Wi-Fi network.
