It's generous of you to make exception for people who are addicted to the dopamine hits that legacy social media have conditioned them to feel they need. Likes are relics of ad-driven, centralized, algorithmic social media platforms. They communicate nothing of actual value. Turn them off in your nostr client's UI and it will completely change your social experience. 

 which clients have this option to turn em off? 

 On iOS you can turn them off in Damus and Nostur. Snort web client also. Not sure about Android.
