          There you go.



          documentclassamsart
          DeclareSymbolFontntxlettersOMLntxmimit
          SetSymbolFontntxlettersboldOMLntxmibit
          DeclareMathSymbolphimathordntxletters30
          usepackagebm
          begindocument
          Huge

          $$phi, bmphi$$

          enddocument


          phi




          Thanks to @marmot pointing out this previous answer by @AlanMunn. As @AlanMunn said in that answer, one needs some basic knowledge about font declarations before performing the trick. This key line of code in newtxmath.sty:



          %DeclareMathSymbolphimathordletters30


          tells us that we should be looking for lines that declare letters. Indeed, we find



          %%%%%%%%%%%%%%%
          % Math Italic %
          %%%%%%%%%%%%%%%
          ... ... ...
          DeclareSymbolFontlettersOMLntxmimit
          SetSymbolFontlettersboldOMLntxmibit
          ... ... ...


          Thus, the suggested solution.
