You can store your camera position under the UI Dots menu. Click on it and select Camera, from the drop-down menu (UI is default). Move the camera to where you want it and click on one of the empty dots. Then if you undo anything and it changes the camera position, just click the same dot that you stored the camera on and the camera will jump back to that stored position. You can store up to 9 dots. 

You can also use the posing camera instead of the main camera. Whichever camera you have selected when you store the position of it, will be affected by the dots. 

eta: The more direct answer, if you have this option, select the camera and go to the Properties tab (next to Parameters tab) and uncheck "Remember changes for undo" if you have that option. That might be a more simplistic approach. Not sure if it's available in P10. Should be tho. I just discovered it.
