Search box without showing all possible values

I have a Power BI dashboard where I need to allow the users to type in a chassis number, the dashboard will then display information pertaining to that. I have tried using a slicer which works, however is also lists all of the available chassis numbers in the dataset (either as list or a dropdown) and I want to avoid making that information public.

Is there a visual or a way that I can allow a user to type in the chassis they are looking for, which if found will filter / display the data, but without giving them a ready made list of all the chassis numbers?

Many thanks in advance.
