The list might not be comprehensive; the following appear in the man page for my local installation of git (version 2.20.1) in the first group under ENVIRONMENT VARIABLES:
GIT_INDEX_FILE GIT_INDEX_VERSION GIT_OBJECT_DIRECTORY GIT_ALTERNATE_OBJECT_DIRECTORIES GIT_DIR GIT_WORK_TREE GIT_NAMESPACE GIT_CEILING_DIRECTORIES GIT_DISCOVERY_ACROSS_FILESYSTEM GIT_COMMON_DIR                  
…so we might want to unset all of them, just in case.
