Hide column until string, then stop loop

[jokr1]

This code is hiding all columns starting from row 3, column 7, where the value is bold.
But I want the loop to stop when row 3 contains the value "x".

How do I add this to the formula?

Sub boldhide()
     
    Application.ScreenUpdating = False
    ActiveSheet.DisplayPageBreaks = False
    For c = 7 To ActiveSheet.UsedRange.Columns.Count
        Cells(3, c).EntireColumn.Hidden = Cells(3, c).Font.Bold = False
    Next c
     
End Sub

sorry, I meant where the value is NOT bold.
