Yes, you can.
In your case, to cross the border by car, you need the following documents:
power of attorney for the right to drive with a notarized note on the owner's permission to leave;
temporary registration card for the right to drive a car;
technical passport for the car;
driver's license according to international standards.
If desired, a person leaving Ukraine can obtain a temporary certificate of registration in his name (it is required instead of a power of attorney from the owner). You can issue such a document at the service center of the Ministry of Internal Affairs. For this, the car owner and a second person need:
passport,
RNOCPP,
vehicle registration certificate.
