Installation of rsh package on RHEL 7.9 (rsh not found)

Hi!
I have RHEL 7.9 running and I need rsh to work (I know about SSH....). What I can see, rsh was removed in RHEL 8 but it seems to be gone already in 7.9 (3.10.0-1160.elt.x86_64, "developer version"). Somewhere I saw that rsh and rsh-server were listed to be included in 7.9 under license "SBD".
In EPEL 7 I cannot see rsh/rsh-server listed, but in EPEL 8 I found them.

So, what to do? Is there an "easy" way to get it running? I want to execute command remotely on a machine that I cannot change. Command shall be:
rsh -l ........
Problem is that if I want to use SSH I assume I need to do settings on remote machine and that is not possible.
