No, you can reject permissions, but not entitlements.
Entitlements are granted (statically, per developer certificate or maybe app ID, not sure) by Apple, permissions are (optionally) granted by users at runtime.
The only way to not have an app making use of an API gated by (only) an entitlement is to never install it.
Of course there could be permissions that are gated behind entitlements, but in this case it seems to be only an entitlement.
And even then, an app can block usage until you allow a permission; ie Snapchat doesn’t need the camera permission to allow you to chat but will block usage of the app until you enable it.
