Namely min_free_blocks_threshold and mc_min_free_blocks_threshold, whereby the latter is used if the number of clean segments is below min_clean_segments, similar to the other mc options. To accommodate your scenario you could simple set a very low value or even 0 to mc_min_free_blocks_threshold. So if the number of clean segments drops below min_clean_segments my patches would be disabled.
