This custom CSS should do the trick:

#badges-management-grid_c4, #badges-management-grid tr td:nth-child(5) {
    display: none;
}

There is a standard caveat to be applied here re: the nth-child() selector, which is that if Docebo would update the table such that the Event was no longer the 5th child, you’d end up hiding whatever was the 5th child instead. You typically wouldn’t be notified about such changes, either.

In practice the above probably applies to the column header as well (id="badges-management-grid_c4"), because the ID is clearly tied to the position in the table.

With all that said, in this specific case I’d be pretty surprised if Docebo’s developers had any intention whatsoever of touching this page in its current form. It’s a legacy page, and I’d expect that any maintenance efforts would be redirected towards completely refactoring this or some other legacy feature.
