Windows 10 StorportMiniport Driver Signing

Hi,

I work in a team that develops custom Storport Miniport qualification drivers meant for internal validation (within the company) of several devices.
The driver is not meant for public release and also will never manage to pass Microsoft WHQL tests due to various custom scenarios.
We have been production signing the driver using a certificate from Symantec. But, the cross-certification chain is expiring from Feb 22, 2021.

Is there any way to Production Sign the driver in Windows 10?
We do not want the systems to run on Test Mode so Test Signing is not possible.

Thanks.

Yes. Attestation signing.
