It sure will! Muratic acid will also eat up almost anything else too.
Further, I am not sure what kind of reaction you would get when
introduced to copper bearing paints. It could prove quite dangerous, or
at the very least, incendiary.

Light sandblasting or heavy (3500 psi) pressure cleaning. But you may
have to sand. If must sand, please educate yourself on environmental and
safety requirements prior to sanding. The dust is unhealthy for just
about anything that lives.

The only way I'm aware of is sanding. The marina's I've used in the past

have

used a DA (dual action) pneumatic sander after scraping and/or pressure
cleaning. Sanding is usually only done if you need a very smooth bottom.

Not

for a normal bottom paint job.
