TL;DR

The most straightforward method is to move the Xsession file from /usr/share/xsessions/ to /usr/share/wayland-sessions/ by:

sudo mv /usr/share/xsessions/enlightenment.desktop /usr/share/wayland-sessions/

Then reboot and select Enlightenment (on Wayland) session in GDM3, SDDM, LightDM to login and check

1. the needed related libevas1-engines-wayland will be installed automatically as dependency.

2. According to ArchLinux wiki -

   To try the Wayland compositor, enter enlightenment_start

3. The same is written in /usr/share/doc/enlightenment/README:

   NOTE: To enable wayland support (still considered experimental and not for regular end users) use the meson -Dwl=true option. To run enlightenment in wayland mode, just log on on ant vt and run enlightenment_start. If you wish to debug and see all the output try using something like screen then attaching to the remote screen session by sshing in etc.

4. All the sources including Gentoo Wiki say all the same about non-stable nature of E17 on Wayland:

   At the time of writing (28 Sept 2020) Enlightenment with Wayland session is not considered stable for everyday use.
