As far as I know, they all allow disabling. In fact, all the ones I have direct experience with require specifically enabling Bluetooth or WiFi in order to use it.
My Nikon D7200 supports WiFi but it's default disabled. Simply enabling the WiFi on the as shipped camera does indeed put it in an open insecure mode, but the Nikon App will allow you to change it ...
I managed to control the shutter remotely (to be more pricise via microUSB cable), while watching the liveview of the camera (D3500), using "Camera Connect & Control" (Android).
It costs 9 euros and it also offers a free trial, so that you can make sure that things work at your end.
