Yes, you could do that already before as well:
sudo i2cset -f -y 3 0x6a 0x00 <VALUE>
<VALUE> is between
0x00 (100mA) and
0x3f (3.25A). See https://www.ti.com/lit/ds/symlink/bq25895.pdf page 32. You can verify the currently set value with
This is also useful to set input current limit to a higher value than the default 500mA when using USB-A chargers.
