You have the option to keep all of your skill endorsements hidden by default:
- Move your cursor over Profile at the top of your homepage and select Edit Profile.
- Scroll down to the Skills & Endorsements section and click the Edit icon.
- Click the green check mark next to Display your endorsements?
- Select "No, do not show my endorsements" from the dropdown list.
- Click Save.
Your skills will still be displayed on your profile. However, the endorsements from your connections will not be displayed. Your connections will still be able to endorse you, but the endorsements will not show on your profile unless you undo this setting.
