Adding certificates to trust list for signature validation

Hello Acrobat Community,

I want to add a root-certificate to the trusted indentities in Adobe DC for multiple PCs in our company.

Without the trusted certificate, users would have to manually add the certificate used for the signature to the trusted identities/certificates list. Until then, signatures from other employees will always be marked as not trustworthy. To avoid confusion of our employees, we want that signatures from our employees are shown as confirmed/legit identities.

The certificate is created by our companies CA.

Here I added it to the trusted list manually:

It should look like this:

Is there any way to add the certificate automatically to the list? Either by Windows GPO or when installing Adobe DC? Where is that list even saved and is there a way to edit it?
