Lift-up at pipe under boiler drum

2 these anchors are boiler drum nozzles with the displacement of 50 mm on the up axis, which makes the large displacement at the under pipe area. However, customers don't want lift-up at the under pipe area, they want displacement at A32 and B09 to be 0mm. Besides, making the guide gap 0 mm on the up axis or adding V-stop in the vertical line will cause no converge error. Is it possible to avoid lift-up and please teach me how to do it. Thank you very much!
