Deleting Mac OS X Recovery Partition

macOS and Mac Apps

Hello all,

Can someone give me instructions to show and delete the recovery partition on my Mac? I have an SD card with the full installation package for Sierra so the recovery is useless for me. I'd like to get the 600 or 700 MB taken up by that back for use on my primary Mac partition. The instructions I found don't seem to work in versions of OS X past Yosemite. If anyone can give me the correct commands to show the hidden drive and safely erase/merge that space with my main partition, I would appreciate it.
