biblatex has the sortname field for that. sortname is only used for sorting purposes and can replace author and editor if the printed name should not be the same as the sorting name.
The biblatex documentation explains the field as follows
[sortname] A name or a list of names used to modify the sorting order of the bibliography. If
present, this list is used instead of author or editor when sorting the bibliography.
Please refer to §3.5 for further details. This field is consumed by the backend
processing and does not appear in the .bbl.

biblatexas a generic tag for bibliographies, so an explicit acknowledgement in the question body that you indeed loadbiblatexwould help. Ideal would be a short example document that shows your current bibliography setup and an example entry that we can play with: That is the best way to avoid misunderstandings and makes it extremely easy for people to get started helping you (it also helps ensure that people test their solutions with your setup): https://tex.meta.stackexchange.com/q/228/35864 – moewe Feb 26 '20 at 20:13
