Father wants to use morphine to be fully sedated

My father is currently in hospice and has expressed that he’s ready to call it quits. We do not live in a death with dignity state so he will have to pass naturally.

As an alternative, he’s asking to be fully sedated so that he can simply be unconscious until he passes. The hospice team informed me they don’t do that.

Curious if anyone has had a loved one with this request and how you handled. Is there an acceptable morphine dose that will get him at least somewhat close to his wishes?

For clarity, I will consult with our hospice team before taking any action. Just wanting to understand the options.
