You can defend yourself.
Those who defend themselves in court should be handled flexibly according to the actual situation, and there are no rules or norms to adopt.
In self-defense in court, we can put forward defense opinions from the aspects of whether it constitutes a crime, subjective thoughts when committing the act, whether it is an accessory, whether it voluntarily surrenders, whether it voluntarily confesses, whether it has no regrets, the severity of the damage, whether it obtains the understanding of the victim, and whether it can apply probation.
For criminal cases, it is recommended to consult a professional lawyer or ask a professional lawyer as a defender.
Legal basis:

(3) Guardians, relatives and friends of criminal suspects and defendants.
A person who has been sentenced to punishment according to law or deprived of or restricted personal freedom shall not act as a defender.
