Welcome to the forum...!!!
I think it depends on which programs?
T2 Laser and BCL (I think) need slightly different Grbl firmware settings. However, with BCL, can set all the needed Grbl settings with one mouse click, so it's pretty easy to re-configure your controller for BCL use.
Both programs can use the same Grbl version which is 1.1e so you won't have to re-flash (not that flashing is that hard or takes that long).
I can't speak for other software, so perhaps you can confirm which software programs you have in mind to run on one PC?
