I am currently configured as follows.

Apartment WiFi Access Point > Wifi Radio - Nanostation LocoM2 (Bridge mode) > Router UTT AC750w > PC.

This gets me online, here's the problem..

I can't access my M2 radio configuration from behind the router, I have to unplug the router and connect Radio directly to PC. Is there a configuration scenario that will allow me to access my radio interface from behind the router?

Your problem is similar to the question how do I access my cable modem behind my router. In general you can't do this. The WAN port on the router is using a IP address assigned by the ISP. This is on a different subnet than the management ip of the bridge.

This means even if you send traffic to the correct IP of your bridge (i think it uses 192.168.1.20 by default) it will send that traffic to the ISP router and not your bridge. Even though the traffic is passing though the bridge the mac address of destination is the mac of the IP router not your bridge so the bridge will assume that the traffic is owned by ISP router.

Now what is really strange is you will see many people that confirm that you can access 192.168.100.1 which...
Log into your Router, check IP assigned to Nanostation and plug that IP into a web browser do you get the nanostation menu?
yes.. Tada solution
No, then if your nanostation works like any other repeater, and your set it as AP mode instead or bridge mode, it will have it own valid IP address from the router and you will be able to access it directly through a web browser.

Now what is really strange is you will see many people that confirm that you can access 192.168.100.1 which is the management ip of many cable modems. Either the modem is somehow intercepting the traffic or there is something special in many routers about the 192.168.100.1. I know it does not work on routers that are configured not to send private ip blocks out the wan interface.

Although it may do nothing see what happens if you set the management ip to 192.168.100.1 on your nanostation.

What generally is done is to place a switch between the router and the bridge. Be sure to place it between the router and the power injector not between the power injector and the radio. You can then plug a pc into the switch and set the ip on your pc to the proper subnet. The router will still continue to function. It really is the same as you do now you just don't have to unplug the router.

Now on some models of nanostations there are 2 ethernet ports I think you could just plug you pc into the second port to manage it...not sure I have never tired it.

Did you not read the I used the word "similar". Is a modem acting as a bridge between the cable network and ethernet is that really any different in function than a device that bridges between wifi and ethernet.

A nanostation is not a wifi repeater is outdoor wireless client-bridge. It has a factory set ip address. It does not use DHCP unless you reconfigure it to do that. He likely installing it on the wan side of his router anyway which does not have dhcp.

The problem is because it is installed on the wan side of the router which is exactly the same problem as acessing cable modem. Now maybe it could be moved to the lan side but this then exposes his machines to the apartment network. The other major reason you generally must install on the WAN side is most public wifi has restricted WDS which means you can not connect multiple mac addresses over a single wifi connection.
