Remove Boot Camp Partition from Mac without Boot Camp Assistant

I have a Macbook Pro with Mac OS Big Sur. I want to remove my Boot Camp Partition, but every forum post I've read says I need to remove it through Boot Camp Assistant. I can't get past the Introduction screen of BCA because "The disk does not have enough space to be successfully partitioned", even though I don't even want to create a new partition.

I've also read that I can remove it using Windows disk management if I boot up in Windows, but I erased my BOOTCAMP disk, so Windows is no longer available.

Is there another way for me to remove my Boot Camp Partition through Disk Utility or Terminal? Or a way for me to bypass the error on Boot Camp Assistant?

Thanks in advance!
