Package biblatex Warning: Conflicting options.
(biblatex) '<namepart>inits' conflicts with 'uniquename=full'.
(biblatex) Setting 'uniquename=init' on input line 12.
The <namepart>inits part of the message might be a bit confusing. In this case it refers to the option giveninits that the MWE loads.
So the warning is telling your that the options giveninits and uniquename=full are not compatible. uniquename=full allows biblatex to add name initials or the full name to citations to make (family) names unique. The uniquename option is shown in action in biblatex, authoryear style: In-text citations display first name initials for certain bibliography entries and discussed in great detail in the biblatex documentation (§4.11.4 Name Disambiguation, pp. 305-311).
With giveninits, which means that given names will always be shortened only to initials, it is not useful to use the full name for disambiguation.
The warning message already tells you one solution. Add
uniquename=init,
to your load-time options. Then biblatex will at most try to add initials to disambiguate names in citations. If you don't want the feature at all, use
uniquename=false,
instead.
