Adding a 2nd MDM Server to Apple Business Manager

When adding a 2nd MDM server to Apple Business Manager that will point to M365, I get to the point of downloading a new server token within ABM. The message that pops up indicating it will reset existing tokens, does that mean it will only reset the token for this MDM and not our other MDM we already have setup and functioning within ABM? I don't want to impact the original functioning MDM. Thoughts on this? Thanks in advance for the help and insight.
