My post feed are redirected

Hello,
I’ve a problem.
When I want to go on my feed post : https://site.com/MyPost1/feed/ i’m redirected to https://site.com/MyPost1/
I want to disable these redirection but I don’t know how.
I’m using WordPress SEO by Yoast but I can’t do it in this plugin (I think).

Is there a solution ?

THanks
