Your initial LrC processing which happens for that camera at import, needs to include "Default" lens profile selection (not "Auto"). For a photo taken with that lens, in the dropdown menu in the lens correction panel, manually choose the desired profile. For this photo the selection will accordingly change to "Custom". Open the same menu up again, and choose "Set profile as default". That teaches LrC about the particular Lens Id resulting from the use of this lens; this photo changes from "Custom" to "Default"; and the desired profile is still used.
And any other photo where the profile is "Default" and that was taken with this same lens on this camera model, will also now and hereafter use the desired profile. This still allows flexible support for other lenses though: you have not fixed any particular "Custom" profile as the overall default.
