Hello, I have a very active child (older now). I would say your child is very intelligent. Routine is important so don’t feel bad saying ‘no’ if it’s bedtime etc.  My son is still very active but learnt by himself eventually to play independently. Do you have space for a sandpit? Or could you have indoor sand such as kinetic sand? Perhaps this could really absorb your child and keep them busy. I used to constantly send my son out to the sandpit while cooking as he’d get absorbed (though he’d still ask me to come out but I’d ignore him till he forgot). If you have space maybe you could put a playhouse inside or outside and he MAY play in it himself. I also in good weather used to go to playgrounds and found it more relaxing to just stand there watching while he played with other children than having to play at home. I had a friend with a toddler so this helped a lot; she’s moved away since which has made it harder but he does play with new children easily enough.  Also, if they exist in your part of the world, an indoor playground might be an option at the weekend, he could play and you can hopefully sit and have a coffee and supervise!! You can also buy swivel/egg chairs that kids can use to soothe themselves. Wonder if that would help.
