We strongly recommend to configure all use-case relevant certificate payloads (trusted certificate / SCEP certificate) in a single Configuration Profile in Jamf.

Add a new "Mobile Device Configuration Profile" and choose "Certificate" as payload. Enter a meaningful name and upload the certificate (for "Select Certificate Option" select "Upload):
Please add another "Mobile Device Configuration Profile" and choose "SCEP" as payload. Activate "Use the External Certificate Authority settings to enable Jamf Pro as SCEP proxy for this configuration profile" and enter the following information:
Distribute the profile to your clients as desired.
