>If you had 8 minute warning for an earthquake, what could you do

That's not how it works. There may be detectable precursors that could actually give warning, but the 8 minutes referenced is the time it takes light from the sun to reach earth. It's immediate in the sense that it is physically impossible to detect that before those 8 minutes have already elapsed and the light is hitting your detectors. You could try to move your detectors closer to the sun to detect earlier, but any signal you can possibly send back to earth goes at the same speed, so it doesn't help.

What if we moved earth closer to sun or more away from sun.

So maybe we are able to detect that at time X there will be solar flares. We know they will be here at X + 8min.

But if we start moving away now from the sun, we will have more time to deal with it.

If it was immediate it should also be immediate even if we moved to 20x distance of the sun, or no?
