Is there a way to change which disk Unreal uses for scratch disk for packaging?

My Editor is installed on D Drive, I’m trying to package the game on D Drive as well, but Unreal seems to want to use my C Drive where I don’t have much space left as a scratch disk. Package fails because there’s no room. How can I switch the package scratch disk to another drive? Thanks much.

Yes, Unreal can default to the C Drive, you need to select the folder you want to packing the game to

How do you do that?
