It's quite difficult to advise because autism is often as individual as the child.
The best thing I can advise for at home is a self regulation zone. Somewhere he can safely let out those feelings. This can be something like a tent in his room or somewhere in the house full of soft things.
Or another strategy could be something to let out any built up physical energy outside.
I would speak to the SENCO about strategies at school. This is a tricky age for any child and adding autism into the mix with sensory issues on top can make it very hard for a child.
Try to be careful what language you use discussing this with him as well. Make sure he is included in conversations about his needs and don't use descriptive words like "difficult" because internalising a message like that can be harmful to him.
Above all what is needed is patience and kindness while still having consequences for behaviours that are not acceptable in a home or a classroom. Put limits and timers on access to screens and have those be reward based the same as you would any child. So that using a self regulation zone and managing his outbursts has a positive outcome for him.
Explain everything even if he gets frustrated with it. Make sure he knows what is happening that day, that he always knows where to find the things he needs and they are consistently in the same place. Whenever there is a situation that might mean a meltdown, take extra time to explain each step and what is expected from him.
Best of luck
