Is it permissible to divide the days of attendance and work in a government job as a doctor if the direct supervisor agrees, knowing that the previous head of the department refused that, citing it as Haram?

The employee is legally bound by the terms of their employment contract, based on the Almighty's saying: "O you who have believed, fulfill [all] contracts," and the hadith: "Muslims are bound by their conditions." Therefore, work hours must be adhered to, and it is not permissible to change them except with explicit permission from an authorized person.
