Is it possible to do in git (squash | fixup) in different ways?

Question

git

Good afternoon.
1) Is it possible to glue commits with the rebase command without going into interactive mode (without -i)?
2) Is it possible somehow with one commit command with options not to mark a commit as squash, but to immediately rebase the commit merging with the specified commit?
3) Fixup differs from squash only in that it omits the commit name?
