Are there any way to skip the next activity using JS

Are there any way to skip the next activity using JS

For example, I have an action like this:
Run external JS => Save file => Run External Bat
The problem is , are there any way in the JS to skip the save file acvitiy ?
What I would like to do in the JS is :
if (some condition) { //Skip the save file activity }
Is it possible or any workaround can achieve the same result? Thanks
