Switching boards for 11th and 12th

I studied from Junior KG to Class 10 in the CBSE board (so basically my whole school life). Now for Class 11 and 12 I might have to switch to the Gujju or Gujarat State Board (GSEB).

The reason is that there are no CBSE schools near my area offering Commerce Maths. So the state board is basically my only option.

I plan to take Commerce Maths in 11th and 12th.

I just want to ask: will switching from CBSE to the state board cause any problems? Is it a big difference in terms of difficulty, teaching style, or exams? Is it worth switching, or will it create issues later?

If anyone has switched from CBSE to a state board before, especially GSEB, I would really appreciate your advice.
