insert active/inactive for all

This should do it.
Just replace the const choiceFader name/string with your desired track.
I added a function to scroll to your choice track and then back to the first selected track in the session before triggering the script.

sf.ui.proTools.appActivate();
sf.ui.proTools.mainWindow.invalidate();

const choiceFader = ["---Master---"];

function scrollToTrackNamed(trackList) {

    // Open scroll to track dialog and enter track name
    sf.ui.proTools.menuClick({ menuPath: ['Track', 'Scroll to Track...'] });
    var confirmationDialogWin = sf.ui.proTools.confirmationDialog;

    confirmationDialogWin.elementWaitFor();

    confirmationDialogWin.textFields.first.elementSetTextFieldWithAreaValue({ value: trackList[0] });

    confirmationDialogWin.buttons.whoseTitle.is('OK').first.elementClick();

    confirmationDialogWin.elementWaitFor({ waitType: 'Disappear' });

    //Re-select originally selected tracks
    sf.ui.proTools.trackSelectByName({ names: trackList })
};


// Get selected track names to reselect later

var origSelectedTracks = sf.ui.proTools.selectedTrackNames;

//scroll to choice fader
scrollToTrackNamed(choiceFader);

// Toggle inserts active state
for (var x = 0; x < 10; x++) {
    if (sf.ui.proTools.selectedTrack.insertButtons[x].value.invalidate().value != "unassigned") {
        sf.ui.proTools.selectedTrack.trackInsertToggleActive({
            insertNumber: x + 1,

        });
    }
};

// If tracks were selected at start of script, reselect them
if (origSelectedTracks.length >= 1) {
    // reselect original tracks
    sf.ui.proTools.trackSelectByName({
        names: origSelectedTracks,
    });

    // scroll to first selected track
    scrollToTrackNamed(origSelectedTracks)
};
