Look up the manual for your current microwave. It may be able to, or it might have some programs that have varied levels of power. Some just don’t have the option, tho, so that might be why.
Thank you, I will definitely check! I don’t think I’ve ever actually bought a microwave, they’ve kinda just been in whatever house/apartment I’ve moved into, so that’s probably why it never occurred to me that that info was probably in the paperwork that came with the machine
