It cannot be bypassed by modifying or tampering with the operating system (OS) because it receives signed device information from the device's Trusted Execution Environment (TEE) or Hardware Security Module (HSM) including the verified boot state, operating system variant and operating system version. The verification is much more meaningful after the initial pairing as the app primarily relies on Trust On First Use via pinning. It also verifies the identity of the device after the initial verification.

See https://attestation.app/tutorial for detailed usage instructions. This is included as the Help entry in the app menu. The app also provides basic guidance through the process. See https://attestation.app/about for a more detailed overview.
