Did you try CARGO_GIT_SUBDIR? See https://cgit.freebsd.org/ports/commit/?id=ab415159b8b9
If that commit message is still unclear check existing consumers:

$ rg -l CARGO_GIT_SUBDIR
Mk/Uses/cargo.mk
dns/dog/Makefile
games/veloren/Makefile
security/bitwarden_rs/Makefile
sysutils/vector/Makefile
x11/wmfocus/Makefile
