You can add this line to your SciTEUser.properties file or an individual Style: line.margin.visible=0 Then save the file and restart the program.
If you search for the word "margin" here you will find other options too: https://www.scintilla.org/SciTEDoc.html
Also, after re-reading your question, maybe you are looking for fold.margin.width=0.
