Restricting a DFF based on Country in Oracle Learning Offerings

We are working in Oracle Fusion HCM – Learning Module and have a requirement to restrict a Descriptive Flexfield (DFF) based on country at the Learning Offering level.

For example:

• If the offering is for US, only the US-specific DFF segment should be visible.
• If the offering is for France, only the FR-specific DFF segment should be visible.

Has anyone implemented a similar restriction or setup?

• Can this be achieved using context-sensitive DFFs and value sets?
• Or do we need to handle it through page composer / EL expressions?
• Is there a recommended best practice from Oracle for country-based DFF restrictions in Learning?
