How to disable the left mouse button from rotating the camera in standard third person template mode?

I’ve been trying to find out how to basically disable the left mouse button click on camera rotate for the standard third person template.

I was not able to find anything useful which seems like a simple operation to perform.

Here is a simple blueprint modification to the camera input which im doing to achieve this. Its probably not optimal or the best approach to this but the only thing i have come up with.

If anyone has better ways to do this please reply.

Thanks
Mark
