XF 2.3 How do I disable sending emails to all users for topics I follow?

[Hareon]

My forum is starting to send a lot of emails. I want it to only send emails to confirm registration, welcome, private messages or recover passwords. At most, if I want to send the emails as communication.

I want to disable the possibility of sending emails to follow topics and resource updates on the forum. I want to leave only the alert. Is there an option to do this?

Not sure if it can be disabled fully but there is an option "Only send watched content alerts/emails to users active in last:" and this could help improve and save on performance
