Divorce after NON EU Family Member getting pre-settled status

Do we know if pre-settled status is still under imigration control or NON EU Family Member becomes independant once they are granted pre-settled status?

Also, if they get divorced after NON EU Family Member getting pre-settled status, does he need to apply again for pre-settled status? or he can apply for settled status when it becomes 5 years from the date of marrige (considering marriage lasted more than 3 years)?

Thank you
