Hello @Kristi Kitz,
Thanks for bringing this subject to the discussion.
At the moment, this functionality is not available. We already have an issue about it in our backlog and the team will look into it!

Right now, I would suggest the following workaround (.oml attached to the reply)
Create a new action on the OnReady Event. Inside, you might want to add a JavaScript just like in the image below.

For the code, I used the snippet:
var column = GridAPI.ColumnManager.GetColumnById($parameters.ColumnID);
GridAPI.GridManager.GetGridById($parameters.GridID)
.features.filter._filter
.getColumnFilter(column.provider)
.filterType = 0; // disable the filter for the specified column
After setting the GridID and the ColumnID (to which you want to remove the filter):

You should end up with something like this:

Hope this answer is useful.
Best regards,
Tiago Pereira
