Signing a Windows executable bigger than 3GB

We are trying to sign a Windows executable, using a PFX file, and are failing because of the file size (3.1 GB).

We are using the latest Signtool by microsoft https://docs.microsoft.com/en-us/windows/desktop/seccrypto/signtool

Here is an example of the command line we are using:

signtool sign /tr http://timestamp.digicert.com /td sha256 /fd sha25 6 /f D:\folder\signature.pfx /p SolidCAM "D:\folder\file.exe"

And this is the error we are receiving: "Error: Store IsDiskFile() failed." (-2147024893/0x80070003)

Any ideas how to solve it? Should we use a different signing tools?
