How install my own serial ports driver without turning off secure mode in BIOS?

Hello everyone, I'm working with virtual serial ports, I have my own driver and has digital signature, but when I try to install, in devices manager appear a warning in the new serial ports, and the driver. The only way to install "correctly" is turn off the secure mode in BIOS.
I'm looking for a solution where I don't have to modify the BIOS settings.

Who signed your com0com driver and how?
Secure boot is not compatible with some signing modes such as self-signing using cross certificates.

If you need secure boot, you'll have to re-sign the driver properly.

I tried two ways, the first is the signing of the maker, the second one I signed with signtool and my own certificate.
which signing mode is the correct one?

I used the following command in a WDK terminal on Win 7, "signtool sign /v /f myOwnCertificate.pfx /t "http://timestamp.digicert.com" ..\amd64\com0com.sys"
that command I found it in the official documentation of Microsoft, I do not know if you have other info about or where can I find it?
