why not do a temporary grab to a dummy widget
(e.g. a label widget or a frame)?

    dummy.grab_set()
    ...
    dummy.grab_release()

:::

if it's okay to explicitly disable just the launch button,
you can use bindtags:

    tags = launch.bindtags()
    launch.bindtags("none")
    ...
    launch.bindtags(tags)
