The cylinder has to roll up the plane on its own!

If the center of gravity of the cylinder does not match the axis, then it is possible for the cylinder to start at the foot of an incline with its CG above the center line. Rolling uphill could actually lower the position of the CG.

Of course, it will stop moving "up" (it is not really up, as the CG is going down, but for onlookers, it seems like it is "up") as soon as the center of gravity is at its lowest position.

The word "up" in your question implies that work must be done on the cylinder, which means that a force must be applied somehow to oppose gravity. An automobile driving up a hill is an everyday example of this happening.

a rolling cylinder has kinetic energy due to rotation and translation. This will allow some "uphill" motion

Otherwise apply outside force in any of dozens of ways.

No, Vincent G had it RIGHT. If the CG is offset from the center of the circle, it will roll up until the CG is at its lowest point. I've seen it happen.

By someone pushing it.

Or someone pulling it
