Digital control CC/CV boost DCDC chip/module?

Are there any hobbyist-affordable non-isolated DCDC boost chips or modules which could be controlled digitally via microcontroller with internal digital CC/CV support? Surely, it is possible to use regular boost IC, stick there bunch of opamps, ADC, DACs... It's a mess and alot of work.

Maybe there are some DCDC modules with LCD displays (like these) which are easily hackable to get full digital control over them? Or I have to use regular boost modules and hack in digital potentiometer/manually sense current?

For this application I need to step up 48V to ~90V with 0-700mA (LED strip) current with 10 independent channels.

Update: ideally this is some sort of IC which I can operate like lab power supply: send via I2C commands like "V=37.32 I=0.371 ON" - and it works in CC/CV mode automatically like a lab power supply. But I2C controlled LED driver which can only do CC would work too, if I can set and sense current.
