play against a computer where the computer only does 1 d4?

is it possible to play against a computer where the computer only ever does 1 d4?
Open a new analysis board, flip the board and make 1.d4 for white, then click the Practice vs Computer button in the lower-right corner. That will start a game versus a bot with 1.d4 already played. You can adjust which bot you play against to suit your liking once the game is started.
