Hello! I could really use some electrical advice on how to swap my lighted ceiling fan to a chandelier, preferably with a dimmer.

The lighted fan runs on a 2-way light switch, 1 for light on/off, and 1 for fan on/off; the fan speed is controlled by pull chain. Both are double pole switches. From what I’ve read, I don’t believe a dimmer can be used on a double pole switch.
Question 1: Can a slide dimmer switch operate independently from the on/off switch? (Just controlling the brightness)
Question 1a: If so, will I need to rewire the circuit to two single pole switches?
Question 1b: If not, do I need to rewire just the one to a single pole switch and then buy a wall plate that covers the unused double pole switch?

Any help/advice is greatly appreciated! Pictures attached for reference as well as the dimmers that work with bulbs I bought for the chandelier.
