Configure Antminer s19 pro to reduce hashrate and power consumption dynamicly?

[ATK1st]

Hi Everyone,

I want to use my extra solar power generation for Mining. I live in Australia and electricity power is expensive and the network buys my feed-in too cheap! My extra production is variable between 0 to 5KW and I want to use only that extra portion. I have an Antiminer s19 pro which uses 3kwh (no ssh access). Its firmware version is "Thu Jun 9 13:06:22 CST 2022" and Log shows "Linux version 4.9.113 (jenkins@nomd-nomd-fwc-bj)" and "type: Antminer S19 Pro". It has 3 boards,

Question is, can I change the frequency or enable and disable Hash boards to somehow control the amount of power consumption quickly (I don't care about the hash rate or efficiency)?

Thanks
ATK
