Demountable walls to make extra rooms?

Hi community. I’m looking to house hack my first property and walked through a couple of properties that have a fair amount of square footage but only 3 bedrooms. I plan to live in one of them thought it might be a good idea to use demountable walls instead of drywall to create extra bedrooms to rent out. Has anyone used demountable walls to add rooms? If so what was your experience and which brands did you use? Do you prefer it over installing dry wall?

Love to hear your thoughts!
