If resistance is fixed in a DC circuit, can voltage still be controlled and changed from one value to another?
If you use PWM, is not DC anymore. What do you mean by controlling the voltage? You can just change the current, as Mechkov said, but it all depends on your circuit.
Maybe Ohm's law (V = I*R) can help to answer this question?

Yes its possible if u want to chage it. You can use pwm techniques.

Yes. It is still possible. DC-DC Converters can be used depending whether you are to step it up or reduced it.
Chaprhay converters that are using or you can take control of your desired voltage level
