Our school counselors are being told that test optional is exactly what it says. However, like everything, you need to work out what rounds and strengthens your application. So if you are prepared and know you will score well on the test then it may be prudent to continue with efforts to try and take the test. If you don’t think it will strengthen or enhance your application then probably good idea to forego. I think the risk of taking the test for a typical kid with no underlying issues is very low so as not really to be a consideration IMHO since they are spaced and masked but that is of course a personal risk assessment. From what you have said you don’t think that your son is an average test taker so this test would not really be a benefit so if I am reading correctly, my advice would be to skip it. HTH
