A natural place to emit these is in, respectively, update_begin_hook and update_end_hook. These two hooks are currently set to NULL (in term.c) for TTY frames. So as a first try, I suggest to define these hooks for TTY frames, and make them emit these two commands. If doing so resolves the problem with flickering on alacritty, we can think how to add that cleanly only for alacritty.
