In a social media post, Boateng stated that he would focus on obtaining his coaching license, which is a priority for him.
Boateng thanked the club and coach Kompany for considering him for the internship, but acknowledged that the focus should be on the team's performance.
Bayern Munich recently won their 13th consecutive match, and the team's leadership had expressed interest in having Boateng as a part of the coaching staff.
However, fans were opposed to the idea due to Boateng's past conviction for bodily harm against his former partner.
A petition against Boateng's involvement with the club gathered several thousand signatures.
Boateng played for Bayern Munich from 2011 to 2021 and made 76 appearances for the German national team.
He won several titles with Bayern, including nine Bundesliga championships and two Champions League trophies.
Boateng recently retired after playing for Austrian side LASK Linz, where his contract was terminated by mutual agreement in August.
