This gets the job done, but just in a potential risk way since Docebo is using incrementing classes instead of meaning based ones, so theres nothing from stopping them from changing what are in 0 vs 1 vs 2 at a later date, but I do not see a better option right now, so just weigh your risk/reward/maintenance appropriately:

.dcb-te-content-details-widget-item-0 {
display: none !important;
}

Thank you very much @Bfarkas, I will have a look and decide! Thank you!
