There are a few ways to go about this. To do this for individual plots, you can use the disableDefaultInteractivity command as below:
x = 0:0.01:10;
y = sin(x);
figure(1)
plot(x,y)
disableDefaultInteractivity(gca)
If you would like to do it for all of the created plots in a session, use
>> set( groot , 'defaultAxesCreateFcn' , 'disableDefaultInteractivity(gca)' )
However, with that method it will reset everytime you start up MATLAB.
If you would like this to apply whenever you open MATLAB, you'll need to implement it into your startup.m file. Here is an example of how you could implement it (MATLAB version 9.7 is 2019b)
if ~verLessThan('MATLAB','9.7')
set( groot , 'defaultAxesCreateFcn' , 'disableDefaultInteractivity(gca)' )
end
