You can try to modify the Exosuit Framework'file from Github: .source\Thing\Building_MaintenanceBay.cs

public virtual AcceptanceReport AcceptablePawnKind(Pawn pawn)
{
if (GetComp<CompPowerTrader>()?.PowerOn ?? false)
{
return "NoPower".Translate().CapitalizeFirst();
}
/*Obscuring this judgment: Is the driver human?
if (!pawn.RaceProps.Humanlike || pawn.IsQuestLodger() || !pawn.IsColonist && !pawn.IsSlaveOfColony && !pawn.IsPrisonerOfColony && (pawn.IsColonySubhumanPlayerControlled || pawn.IsGhoul))
{
return "PawnNotQualified".Translate(pawn.Name.ToString()).CapitalizeFirst();
}
*/
return true ;
}

But I must say: I tried to modify it this way, and although it allows the synthetic to enter the Exosuit, the Exosuit texture is transparent, and it feels like the synthetic is floating in the air.
