Can't get a manual clutch to work in advanced vehicle template.

I’m currently making a drifting game in UE4 (4.26) using the Advanced Vehicle template and the other day was trying to add a manual gearbox. I got the manual gearbox to work but simply can’t find any way to manually engage/disengage the clutch (to be able to clutch kick and stuff). I Googled a ton of things about it but couldn’t find anything. Is there any way I could add a manual clutch to this template? and if it isn’t possible then in what other ways can I add a manual clutch?

I believe the only way is to have an input that put the car in Neutral, but I haven’t tried it yet.
I hope they fix the automatic reverse that does that even if you are in high gear, it should brake first and then start the reverse once you stopped.
