Hello aspirant,
No, you can't change from State Board to CBSE Board after completion of your 11th standard mid-term . If you have taken admission in 11th standard in State Board then, you have to study both 11th and 12th standard from same school without migrating to another school. This is because the subjects and course wise syllabus that comes in class 11th is not as completely same as in Class 12th.
If you have to change the board, then it is actually better to change that immediately after class 10th. change of boards in Mid class 11th is not possible.
since you are studying in class 11th, so to know more about the Career options to pursue after class 12th, you can follow the below mentioned link to know more : https://school.careers360.com/articles/courses-after-12th
I hope that this will help.
