font data entry

Hello,
we are developing an ESG application on behalf of our client.
Due to internal corporate branding policies, the client requires that all data entry areas use the Montserrat font (Light and Bold).

The font has already been uploaded in the Oracle PBCS settings and is successfully used in the Report section.

Issue:
We now need to apply the same font in the data entry forms, but it does not appear among the predefined fonts available in Oracle PBCS.

Requests:

Is it possible to use a custom font (in this case, Montserrat Light/Bold) within data entry forms?

If not directly possible, are there any workarounds or alternative solutions (e.g., CSS, scripting, or configuration options) to achieve a similar result?.
