Ahhh . . . I hadn't caught the "breaking the already broken" idea.
I will try this later since I just installed CATALINA on the SSD and it will all be erased again through the process "breaking the broken" drive(s).
The procedure in the link you provided takes seconds, BUT the re-install of the OS takes about 45-60 minutes. I may even consider going back to MOJAVE since CATALINA does not recognize a dozen 3rd-party apps I like to use (i.e. I get the icon with the slash through it showing that it will not function with the most recent OS).
** This is the message I get in Terminal if I try to locate Volume Groups (as per the article) using "diskutil cs list" :
No CoreStorage logical volume groups found
