In two layer pcb sometimes vcc wire is insufficient.
I want to use the gnd wire with “via” like vcc.For this, I do not want to cover the entire pcb board GND layer completely.
How do I overlay the part I want as gnd
Does it mean you want to have a copper zone with VCC instead of GND?
You can assign any net to a copper zone.
However in most cases it’s best to have GND plane return path with VCC distributed with tracks, using decoupling caps close to powered components.

I want to switch the trace of power to the lower layer when my passageway is blocked,
then I want to switch from a suitable place to the top layer again.
Now that gnd is mixed with vcc, the automatic gnd overlay option takes up all places, so it will see it as gnd, as it did not see gnd traces as vcc before.
I want to cover the region as gnd for him.
Do you need to regenerate the copper pour (press B) to allow for the trace you routed through the GNC plane?
I did not understand
I understand this to mean that you routed a VCC trace (from top layer, to bottom, back to top) through a GND plane and this appears as if the trace and the plane are “mixed”. To “unmix” this you just need to have the copper pour redrawn - that is done with the B key. KiCAD then makes sure the VCC trace is not “mixed” with the GND plane.
No idea what you mean with this.
