DNSSEC is a means of authenticating the data receives was not tampered with, such as MITM attacks, thus ensuring data integrity. It uses PKI but it’s not an alternative to DoH or DoT which encrypts the DNS traffic, either over HTTPS or TLS, providing confidentiality.

DNSSEC can be used in conjunction with DoH or DoT to achieve the Security CIA triad - Confidentiality, Integrity, Authenticity.

Unfortunately its not a third party module but manufacturer built-in features.

Modern cars are internet-enabled, allowing access to services like navigation, roadside assistance and car apps that drivers can connect to their vehicles to locate them or unlock them remotely. In recent years, automakers, including G.M., Honda, Kia and Hyundai, have started offering optional features in their connected-car apps that rate people’s driving. Some drivers may not realize that, if they turn on these features, the car companies then give information about how they drive to data brokers like LexisNexis.

One good thing that came from this post is I learned about Jshelter and have decided to give it a go.
