Set a search area (without selecting it)

Is is possible to set a search area on a different selection/sheet/workbook without leaving the current selection or leave the current sheet?

I want to use it in conjunction with the

    Set rngFound = Cells.Find(What:=txbNumber, After:=ActiveCell, LookIn:=xlFormulas, LookAt _
        :=xlWhole, SearchOrder:=xlByRows, SearchDirection:=xlNext, MatchCase:=False)
        
        If Not rngFound Is Nothing Then

...........

Thanks
