Found it:

toolbox fn GetSheetWindowParent(WindowRef inSheet, WindowRef * 
outParentWindow) = OSStatus

//
//
//

local fn HideSheetWnd(sheet as long)
dim as WindowRef @ sheetRef, parentRef
dim as OSStatus    osStatus
'~'<
get window sheet, sheetRef
OSStatus = fn GetSheetWindowParent(sheetRef, parentRef)
osStatus = fn HideSheetWindow(sheetRef)
osStatus = fn SetWindowModality(parentRef, _kWindowModalityNone, 0)
end fn
