MATLAB with OpenGL through terminal?

I'm curious if it's possible to get MATLAB running with any form of OpenGL from the terminal. The issue is I am currently running MATLAB through a ssh client and incapable of running the normal desktop mode. I received a warning when creating some figures that OpenGL is not available when running through the terminal and there were lines running all over the figure's graphics objects.

When you are running MATLAB from the command line (any SSH client), you can use 'nodesktop' mode to run MATLAB command line mode. Use the following command to run MATLAB from terminal:
>> matlab -nodesktop -nosplash
There is no need to alter 'opengl' behavior until you are trying to launch some figures. You can disable launching figure windows by specifying the '' startup option. For example,
>> matlab -nodesktop -nosplash -noFigureWindows
Also, if you want to alter opengl behavior or want to execute any script while launching MATLAB, you can use the '-r' flag and execute the script. For example,
>> matlab -r "opengl software"
Refer to the following documentation link for more startup options:

Same problem here. I want to produce images by running a script via an ssh terminal. In the script the following lines are called:
hf = figure('visible', 'off');
clf(hf);
ax = axes('Parent', hf);
imshow(I, [], 'parent', ax)
hold(ax, 'on')
contour(structure, [.5 .5], 'b-', 'linewidth', linewidth, 'parent', ax);
exportgraphics(ax, [path '.png'], 'Resolution', 600);
This results in the warning:
Warning: MATLAB has disabled some advanced graphics rendering features by switching to software OpenGL. For more information, click <a href="matlab:opengl('problems')">here</a>.
and produces images with huge black padding.
Running this script locally in the MATLAB IDE, however, does not have this issue.

I have the same problem -- now working from home makes a significant problem. Mathworks support washes their hands with the usual "not supported" feature to run matlab over ssh. What?
Paraview works with server-side rendering so I can use the GPUs on my server, but Matlab does not...
