My dad is a Vietnam veteran. I am his his durable power of attorney, how do I prevent him being placed in a state facility?

He has had dementia for 2 1/2 years. I have been trying to get him the VA, adult protective services, the police, etc. I have gone to so many resources for help. No one helps. He is rapidly declining. Suddenly I get informed that the state is now going to place my dad into a state facility! I told them I have his VA facility and  just need the VA Dr to sign off on his assessment. I'm not sure what else to do. I have even spoke to VA pro-bono attorneys, no one has any answers other than to put him in the car and leave him at a facility. He  will know where he is, he recently said I am not going to a nursing home to die.
He is getting very agitated and not eating (except ensure). He doesn’t remember anything on most days. I really hope someone on here can give me advice. Thanks.
