NX Steep Containment Method- None is missing in latest NX version.

Steep Containment Method- 'None' is missing in latest NX version. This option was available in NX11 and previous versions.

 The Steep Containment Method - 'None' has been discontinued and hence this option is not seen in latest releases of NX.

If the similar setting is desired,  the following settings can be used.

Method: Non-Steep

Steep Angle: 90

This option will enact as same as the Method - 'None'
