AWS Code deploy in Virginia region and ec2 in singapore region

I am learning AWS code deployment. Currently, I have a test and prod server in the Singapore region. I want to use deploy my code in the prod server.

I found that code-deploy is not available in the 'Singapore' region, so I switch to 'Virginia'.

So when I am configuring code-deploy then I am not finding my prod server in "attach your ec2 instance".

I am sure it is because of differences in regions.

Can anyone help me with how can I use code-deploy even if I want my server to be in the Singapore region?
