Formatting a large SD card is taking time. What happens if I pause it?

A few days ago, I formatted an SD card with Mac OS Ventura to make it bootable. Then, I wanted to reverse this process and use the SD card for transferring files again. So, I followed the instructions here: https://apple.stackexchange.com/a/280650/456222 Now, this SD card is 512GB. The process is taking a long time, projected to take 1-2 days. What happens if I prematurely cancel it? Is there a way to pause and resume the process?
