AppAttest -- Can a Swift program that uses DCAppAttestService be run on Linux?

I need to be able to run the code that issues an Apple **attest** but not on Apple OS -- on Linux. Or, at the very least, on a MacOS **VPS** -- not a **physical** device.

import DCAppAttest

func generateKeyAndAttestation() {
    guard let attestationKey = DCAppAttestService.shared.generateKey() else {
        print("Error generating attestation key.")
        return
    }

    // Generate a nonce (you may need to use a more secure source for your actual use case)
    let nonce = Data.random(count: 32)

    // Prepare the data to be attested
    let dataToAttest = "Data to be attested".data(using: .utf8)!

    // Concatenate nonce and data
    var attestationData = nonce
    attestationData.append(dataToAttest)

    // Use DCAppAttestService to attest the data
    guard let attestation = DCAppAttestService.shared.attestData(attestationData, withKey: attestationKey) else {
        print("Error generating attestation.")
        return
    }

    // Print or use the attestation key and the resulting attestation
    print("Attestation Key: \(attestationKey)")
    print("Attestation: \(attestation)")
}

I expect there to be new customers daily, therefore this code will be run regularly. Therefore, using an Apple **physical device** for this, if indeed required, will be inconvenient. 1) I haven't found a clear answer as to whether or not DCAppAttestService must be run **only on** MacOS/iOS . 2) And whether or not it has to be a **physical** Apple device or will any VPS running one of the latest OSX do too? I'm aware that validation, verification of **attest-s** can, indeed, be run on Linux. This will the 2nd step. My question, however, about the code that issues, generates **attest-s** initially -- the 1st step. --- https://developer.apple.com/documentation/devicecheck/dcappattestservice
