Hi Raquel Meyers‌,

It can be done using the below Custom CSS definition as shown below:

.nf-pp-ac-tooltip{
display:none !important;
}

Thanks so much Chaitra B C  So easy when you know how

Just wanted to add a follow up note on this. It may help others in the future.

This works perfectly until you apply apply a rule to disable the field or the panel it is in.  The large pop up is removed but a single line popup is still visible (again, only in new and edit modes). Oddly, if you set the Control Mode for the field to 'Display' it doesn't happen, You can then apply a disable rule (if still needed) to the panel with no issues.

Hi everybody

I want to change value in hover panel on people picker such as add preferred name  in this panel.

I don't want to hide it.

Thank's for all
