I think for RH124 most of the Lecturer/Curricullum can be done without script to be honest, just try step by step the lab guide and install a fresh clear RH Developer Edition/CentOS 8(Stream or normal is fine), then you can try to create user, apply permission, set up SSH, or even do anything else.
The very simple way is having linux Host and Linux Guest VM, then you can go, as the ssh could be don from Host to Guest or otherwise. Other than it, I think you only need the RH124 Book/HTML book to learn more. When outside the labs, I never set up VM / re create it, because one machine with Linux OS(Either RH, Debian, CentOS, Ubuntu, etc), have the same capabilities for doing RH124 lab guide.
Some folk in this forum create a VM Bundle from RH labs, but I won't recomend it, because it's hard to debug when there's a problem that come on the VM and no official documentation that will help to debug it.
Anyway to reach RHCSA, I recomend you to take RH134, as many exam hands on is on RH134, RH124 is only the introduction. Other than that I think you can prepare by checking list the ability that you need to accomplished when RHCSA Exam on this https://www.redhat.com/en/services/certification/rhcsa link. Are you ready or remember all the stuff on that page?
Tips for RHCSA, when you don't remember the command
[user@foo ~]$ mandb
[user@foo ~]$ man
will help you a lot on exam, that's all tips I can give to you. Other that it, practice more, use Linux Desktop as daily driver, ditch windows (oops, personal preferance), and prepare more for RHCSA
Good Luck!
