Open the CMD command line as an administrator, and then enter the command to turn off the forced driver signature: bcdedit.exe-set load options ddissable _ integrity _ checks.

Restart the computer after completion, and you can use the driver without digital signature on the 64-bit Win7 system at any time. This operation reduces the safety factor of the system, so it is not recommended to shut down all the time, nor is it recommended for inexperienced users. Cultivating good safety awareness is the first step of safety. I hope it helps you!
