Is it possible to change the default values ? Only for test purpose

The level is defined by the
CONFIG_ESP32_BROWNOUT_DET_LVL_SEL project configuration option.

No, because the voltage levels are fixed in HW by enumeration values of the
RTC_CNTL_DBROWN_OUT_THRES register. See page 718 of the
reference manual.
