So, unsure if this will be helpful, but someone I know has a Samsung Galaxy S24 with the latest Android software update and they downloaded Avulsion on their phone.
For them, they had the same error as you, and there's a drop down button or arrow that expands and lets you read the entire message and it should say "Install anyway." They were able to download the game just fine despite the error.
If there's nothing like that, then your specific model does not allow it, which is indeed the case sometimes, and why the only way to know if an app will work on a specific model is to download it.
