How to get not name related field in list

[Zuzz]

Please, screenshot in attach.
url /api/v1/Enitity1?select

returns related "entity2sNames":{"62cbe31630ee5149d":"Entity2_22", "62cbe3086e06d6e27":"Entity2_11"}

Is it upgrade-safe way to return another (not name) related field, like

"entity2sSomeNotNameRelatedField :{"62cbe31630ee5149d":"NotNameField_data1","62cbe3 086e06d6e27":"NotNameField_data2"}
