Target /opt/homebrew/share/dbus-1/services/org.a11y.Bus.service
is a symlink belonging to at-spi2-core. You can unlink it:
  brew unlink at-spi2-core

To force the link and overwrite all conflicting files:
  brew link --overwrite at-spi2-core

To list all files that would be deleted:
  brew link --overwrite at-spi2-core --dry-run

dbus and at-spi2-core shouldn't conflict. That needs to be fixed before merge otherwise it will break multiple formulae.
