As a new NSIS user, I have defaulted to the HM NIS Edit wizard to create my installers so far. The default output takes advantage of MUI, which has been very useful to me. It also, however, includes a components page from the MUI macro library, so I cannot pick and choose which components are mandatory. I have looked at this question: How to make a SectionGroup mandatory in NSIS script, but I'm not sure where to put it in my code below, or even how to modify the wizard's output code to include it. The installer is for several apps with distinct (selectable) executables that all require the same (ideally mandatory) support files.

In short, I need to know how to make the Support Files section mandatory, without losing the GUI. My only experience, though, is with the above-mentioned wizard.
The SectionIn instruction is used to assign sections to install types (Combobox on the components page) but it can also make sections read-only:
Section "Support Files" SEC01
SectionIn RO ;Make it read-only
SetOutPath "$INSTDIR"
SetOverwrite try
File "..\Support\File\Path\file.txt"
SectionEnd
