[GCP]Why can't I see the GPU selection button on my VM instance?

I want to use GPU in Windows VM. However, the GPU selection button is not active when creating the instance. Currently, I applied for GPU(k-80) as a quota and got 1 allocation. Of course, I received mail. Some of the answers asked me to check all regions, but all regions on the quota application page were disabled.

What's the problem?

To my understanding the E2 instance type (as in your screenshot) cannot be paired with a GPU.

From the machine types GCP documentation:

You can attach GPUs to general-purpose N1 machine types or accelerator-optimized A2 machine types only. GPUs are not supported for other machine types.

Also consider the regional availability of various GPU types.
