Is it possible to block the phone app on iPhones?
We have no cellular service and I have tried sending a "some apps not allowed" config blocking the phone. But the device remains able to call 911 services. Can the phone app be completely disabled and blocked?

According to what I found, the answer is 'No'. You can turn off certain 'quick-call' features, but by law you can't turn off the ability (in the US at least).
According to United States federal law (47 CFR § 9.10), every cellular phone sold in the U.S. must be able to call 911, even if the calling phone is not subscribed to the closest available wireless network. That means even phones linked to the wrong carrier in the region or those with no SIM card can dial 911 and reach a Public Safety Answering Point (PSAP), such as a local emergency call center.
