Basics first setting, HTTP to https , and broti

hi, I’ve just set my domaine, an in the first basic setting I’m asked to set https BUT,

  • My domaine name hosting is frorm "ionos.fr.
  • My website hosting is to "hostinger" and force HTTP to HTTPS is activated here.

I wonder if it’s good to activate it too on clouflare , 2 activation Is maybe to much …
and i’ma asked for https broti should I say yes ?

Thank you
