on Satellite 6.12 and that options suggested there does not work:

[root@e16-h12-b01-fc640-vm1 ~]# satellite-installer \
> --enable-foreman-plugin-rh-cloud \
> --foreman-proxy-plugin-remote-execution-ssh-install-key true

[root@e16-h12-b01-fc640-vm1 ~]# rpm -q satellite
satellite-6.12.0-4.el8sat.noarch

What I used is:

[root@e16-h12-b01-fc640-vm1 ~]# satellite-installer --enable-foreman-plugin-rh-cloud --foreman-proxy-plugin-remote-execution-script-install-key true
[...]
Success!
