We have a requirement to restrict the OOTB functionality of resizing the designer studio portal by dragging portal scroller situated at left navigation. After checking with developer option we can see that two classes are getting rendered at runtime. "screen-layout-region screen-layout-region-main screen-layout-region-main-sidebar1 screen-layout-region-resize ui-resizable" and "class="screen-layout-region screen-layout-region-main screen-layout-region-main-middle not-nav dc-screen-layout-region-main-middle-notab".
Kindly have a look. We want to have this feature restricted for our portal.

Just so that I am clear. You want to disable the resizable area noted here?
If so, I do not believe there is any OOTB configuration to disable this. While there is an option on the screen layout harness it will not be useful since we're talking about the designer studio harness (This is locked behind a final rule, so it is not available to customize)
As per our client's requirement we need to have one functionality which is on click window resize and collapse, but the second functionality which is manually resizing the screen by dragging the verticle bar towards right or left that thing is needed to be restricted.
