Shalom.
Some discussion of the concept of an eved Hashem can be found here:

My question is: Can a Gentile become an eved Hashem without undergoing gerus?
This question was prompted by the following considerations:
(1) Israel is described in multiple places as HKBH’s servants. Might these verses imply automatically that Gentiles are not?
(2) I am not aware of Gentiles being subject to the laws regarding the piercing of the ear, which would imply that they are not servants in the same sense as Israel (see second article).
(3) Restrictions on Gentile Torah study would seem to preclude the ‘revising 101 times’ that is said to be the mark of an eved in the second article.
(4) On the other hand, Gentiles are free to take on optional mitzvot (Rambam), which would enable them to fulfil one of the conditions of an eved cited in the second article (going ‘beyond the letter’). And clearly there are Gentiles who are free, and thus not encumbered with the status of being a ‘servant of a servant’ (which, according to the second article, disqualifies someone from being an eved Hashem).
Many thanks for your time.
