For American citizens who are worried about whether they personally can get to vote, you can go to
https://www.vote.org/ (see
https://en.wikipedia.org/wiki/Vote.org with links to various news coverage to verify) and spend 5 minutes checking whether your voter registration is still valid/existing, register to vote if it's not, and request a mail-in/absentee ballot to be sent to you if you want. They service all 50 states. This should take care of all COVID concerns, if any, with plenty of time to spare before the election (79 days from now).
IOW, you can basically solve this problem for yourself right now and be done in 5 minutes if you know how to. And now you do.
You can also share this link with others. I think this is about the most effective difference it's possible to make for most individuals who are concerned about how the technical procedures of election will be handled. The rest is kinda locked-in already unless you're on the local election board or whoever handles these things setting up tables, booths, and boxes.
I find it highly unlikely that arguing about this issue is going to change anyone's mind in terms of who they vote for. IOW, it's hard to imagine how suffrage and election processes would become a special interest issue or in any way tip the scales for anyone's vote, but perhaps I'm mistaken about this.
