Question How to force 12kBTU solar mini splits to work at full capacity in cooling mode?

I have been using EG4 12k BTU hybrid mini splits (R410a) since late 2024. They work well , yet I have an issue with how the inverters modulate their compressors. It seems that the compressor power output cap is mainly driven by external temperature regardless of the temperature gap between the set indoor temp and the actual temp in the space. The result is that during cloudy humid days when the external temperature drops below 90 deg F the power is modulated down to 40-50% (400-500w power draw from grid) and the delta T on indoor unit falls to 15-17degF. On hot sunny days with temps reaching 100F and above both units I have can reach 80-100% capacity (750-850w power draw) and indoor unit delta T jumps up to 22-25degF in Turbo/Auto fan mode. Question: Is there any way to force the mini splits to to work at full capacity without modulation? that would be very useful to cool/dehumidify quickly the space if needed even on cloudy below 90degF days. @ EG4 Eric - Any help would be appreciated.
