What is a digitally signed driver?
Claiming that a specific driver is digitally signed means that the vendor guarantees the authenticity of the data that will be installed on the system and blocks any modifications (or updates) that are not from the person or company that created it.
By default, the “Windows requires a digitally signed driver” error occurs whenever the user tries to install third-party drivers, without a digital signature and without proof of the security of their data — given the possibility that they are malicious software disguised as drivers.

Windows allows the user to proceed with third-party driver installation by disabling digital signature verification enforcement. Although this option is not recommended, it is possible for an unsigned driver to be genuine or healthy and to enable a hardware’s capabilities. See below how to proceed:
Remember that all digitally signed drivers are verified and are genuine. It is important to be careful when installing uncertified drivers as you risk compromising your data and computer security.
