What is the ruling on establishing a "Secret Companions' Eid" that resembles the concept of "Secret Santa"?

Celebrating what is called "the Secret Companions' Eid" is impermissible, because Muslims have only Eid al-Fitr, Eid al-Adha, and the day of Jumu'ah (Friday). Any celebration of another Eid is considered an innovation (bid'ah), whether it is done to draw closer to Allah or as an imitation of disbelievers if it is a customary practice, because the creation of innovated Eids is an act of the People of the Book. This celebration is a clear imitation of the disbelievers' celebrations of Santa Claus. Allah replaced the two days of Jahiliyyah for the Muslims with Eid al-Adha and Eid al-Fitr, and "whoever imitates a people is one of them."
