I remain unconvinced that the Reformed Baptist position is dispensational in any form. Firstly the 1689 Baptist Confession was written about 140 years before dispensationalism was 'invented'. Further a careful read of ch 7 of the 1689 confession will reveal a carefully constructed covenant theology. I was argue that the main difference between ch 7 in the Westminster Confession and the 1689 Baptist Confession is a difference over a historical-grammatical Christian hermeneutical method, rather than the covenant itself. Here is a helpful clarification https://contrast2.wordpress.com/2017/05/31/is-1689-federalism-dispensational/
