Good question, but no. The strict scrutiny standard would apply. They all were under emergency declaration I suspect and no, emergency declaration can only suspend constitutional rights where there is a compelling state interest. No such compelling state interest mandated the suspension of longstanding state law regarding how absentee/mail-in ballots were executed. Even the Wisconsin Supreme Court threw this argument out when two county election officials told everyone to declare themselves involuntarily confined, which allows voters to skip ID and signature requirements. The state court said that was illegal and dangerous. Hard to argue for a compelling state interest when the vast majority of Trump’s 74,000,000 voters came out on election day and had two months leading up to the election to vote in person with no threat to health.
