Hello ! This is a known issue, and we've filed a case with our internal development team for review, CPANEL-37171. You can find more information on this case, as well as follow for updates here:

I followed an article from cPanel that helped.

Procedure
To enable this globally, add a new file ending in .conf such as http2.conf to the Nginx configuration folder located in /etc/nginx/conf.d and add the following contents.



server {

listen 443 ssl http2;
listen [::]:443 ssl http2;

}


Save the file and verify the Nginx configuration. Then, restart Nginx as well as PHP-FPM.

nginx -t

/scripts/restartsrv_nginx ; /scripts/restartsrv_apache_php_fpm

I then checked my file:
tail -f /var/log/nginx/access.log

and it showed:

HTTP/2.0

Even gtmetrix reported all is good now with http2
