I think most if not all the actors on the panel at last night’s FYC event are eligible (plus Penelope and Finn). To be eligible for supporting, actors need at least 5% of the screentime which for ACS is ~25 minutes. The ones that are on the cusp are Judith, Jon Jon, and Max, and we’ve already received confirmation Judith’s eligible and FX is planning a big push. I assume the other two can also submit given their presence on the panel, as opposed to Mike Farrell who wasn’t on the panel but attended the event anyway.

The Gold Derby predictions center has Edgar and Penelope for supporting, though this early in the game some of the placements are guesses by the GD editors. If they were able to get early confirmation for Judith they could’ve also gotten confirmation for Edgar and Penelope which categories they would submit. It wouldn’t make sense for Edgar to submit for lead anyway because 1) despite being promoted as part of the main cast he’s had less screentime than other supporting actors like Cody or Finn and 2) Darren is a strong contender in lead and wouldn’t benefit from vote splitting. Penelope could go lead if they wanted to make way for Judith in supporting though.
