For now keep doing partial water changes until the cycle finishes. Don't
disturb the gravel or filter material as the good bacteria are tying to hang

Actually, they *should* vacuum the gravel during the cycling period.
The nitrifying bacteria secrete a glue like substance and adhere to
every surface. They are NOT going anywhere. Vacuuming gravel isn't
going to budge them.
It would do more harm to the health of the tank *not* to vacuum during
a cycle.
