AR Build error in Unity 2020.3 Editor

Hi, Building basic AR app in unity using Image target and Vuforia. i did not install any package for Ar in unity like (ARkit, ARCore, ARFoundation). When building for Android showing error "ARMv7 is not compatible with the ARCore version included when using the "Include ARCore Library" option in the VuforiaConfiguration. To use an older version of ARCore which supports ARMv7, please include ARCore manually in your project instead."
