Not according to my understanding from Pilot Institute. You must be able to look up, see the aircraft, and see which direction it’s going, not watching it 100% of the time. If I’m wrong, someone please correct me.
NOTE: This is US-specific, and doesn't represent the requirements in other countries.
See 14 CFR § 107.3. It's not possible to satisfy the requirements of (a) if not directly observing the aircraft, especially if it's moving. This is why FPV requires a VO even if the drone is always within VLOS were they to take their
goggles off.
