No, you cannot disable it selectively. What I often do (since I have almost no controls installed in most of my IDEs), I just open the form, tell Delphi to ignore all errors when loading dfm, edit my source codes and make sure to check in dfm for my source code management system.
You can try to save read-only dfm in order to avoid erroneous validation in dfm using remote controls, but there is a drawback: every time you try to save the source code, an error occurs in the IDE regarding the readonlyness file. If you press Ctrl-S or Shft-Ctrl-S as often as I do, it quickly becomes a nuisance.
When I need to change dfm, I do it in text mode or install controls, modify and submit dfm. After that, I'm free again to remove controls and just work with the pas file, ignoring / reverting any changes to dfm.
