If I was not in the US for the whole of 2020 and if my child is a US Citizen, can I opt for Child Tax Credit and EIP?

I'm a non resident - was not in the US for the whole of 2020. I did not have any income in US either. I wanted to submit 0 tax return. That's when Child Tax Credit came into picture. Since my son is a US Citizen, can I opt for CTC and EIP?

 

Thanks
