We cannot remove the option to "Enable HTTP/2 protocol" since it is supported in Nginx. If you want to use HTTP2 module in your site then you can switch from Apache 2.4 to Nginx web server and enable the option from Nginx settings.
Also we don't have update about when it will be added back. Once they add the module back in Apache 2.4 prefork mpm then we will as well provide it.
Let us know if you need any further information from us. We are happy to help you.
