Ale,
POV in a novel is an art form and there are many options available.
Diana Gabaldon for instance write her Outlander novels in 1st person for the MC and 3rd (usually tight 3rd) for all the other characters.
There are POV handoffs, POV bobbles(errors).
Even head hopping from character to character done by people like Nora Roberts.
The one rule I’m aware of is you can do anything as long as you do it well.
If you’d like examples, let me know.
