While not exactly pause, but isn't playing with scrub_delay works here?

vfs.zfs.scrub_delay: Number of ticks to delay scrub

Set this to a high value during working hours, and set back to its normal (or even below) value off working hours. (maybe resilver delay, or some other values should also be set, I haven't yet read the relevant code)
