Prevent cisco switch from forming a connection with another switch

This may be a silly question. And i'm probably going to be redoing the network at this location but I thought I would just ask. Once i redo the network the question probably wont be relevant.

We have 3 offices connected via wireless bridge. There are a bunch of netonix switches up there connecting the wireless bridges together. I'm installing an industrial cisco switch in the mix. The issue is that one of the switches at the physical office is configured as an access port instead of trunk. When I bring up the cisco switch that connects to a netonix, it doesn't really see the netonix switch and attempts to make a connect to this switch that's configured as access port - i get a port mismatch on the both switches. Right now I can't configure both switches as trunk ports because at the physical office there is also an untagged vlan on the router. We're planning a trip up to this site and i plan to tag the traffic in the office so i can trunk both ports.

But I got to thinking is there a way on the cisco switches to somehow just deny a connection being formed but allow all other connections? port security?
