Stated plan

Attack the rook with the king while maintaining control over the a3 pawn's promotion path.

Reasoning

The black rook on d3 is undefended and adjacent to e4. By playing Ke4, White directly attacks the rook (forcing it to move) while also solidifying support for the d4/e5 pawns. The bishop on d5 already covers the a2-square, preventing the a3 pawn from promoting easily.
