I'd challenge you to consider that take home tasks are better for some interviewees, but others would do better to have that task done as part of the interview (in-person, video). Offering an option (maybe even ahead of time) allows the individual to play to their strengths and situation, and properly designed (and with good questions/exercises to ensure people who are just good interviewees don't BS their way through the process) it shouldn't make much difference which option the interviewee chooses.
