Self-study BTT/FTT + School practical lessons?

Hi all, planning to get my Class 3 (manual) licence. Trying to understand the whole process and I keep seeing e-lessons, mock tests etc when looking at course details on sch websites.

I just want to book btt and ftt without any of that stuff, and then proceed with practical lessons from sch instructors. Is there anyway to get that done? Looking at CDC Ubi but I don't see a course that fits. Is it possible to do btt and ftt in one school, then switch over to another school for practical lessons with sch instructors? Any advice appreciated!
