If I do not identify as either male or female, can I request that my gender remain undefined, fluid or both?

In Colombia, Decree 1227 of 2015, Constitutional Court T-033 of 2022 and the Single Civil Status Registration Circular version 9 (14.4.1) allow a person to register only one sex: Female (F), Male (M), Non-Binary (NB) or Trans (T). Other options are not supported.
