Email aliases , pgp and e2ee

is there a way to receive pgp encrypted e2ee emails to email alias ? for example i have proton mail address and want to receive an email to my alias while using my pm public key (right now simplelogin strips them because it shows main address) , is there any alias provider that modifies the pub key’s uid to the alias like explained here : Reddit - Please wait for verification ? right now you can attach your pub key to simplelogin but it will receive unencrypted email from sender and encrypt it , but i want e2ee (easiest way is to send from main address directly i know , but i want to use an alias for extra privacy)
