I want to change pull-up resistors from 10k to 4k7 (4700) ohm.
Which params should i change in library?
BME680 Which params should i change to lower pull up resisto

Those are physical resistors and you would need to change them on the board itself.

yes i know i mean i changed them onboard and i am now getting much lower values.
Previously i was getting million ohms to ten thousand ohms (between 2X.XXX - 2.000.000) now i am getting several thousand ohms.
I removed Serial.print(bme.readGas.. / 1000) part. Now it's giving ohms rather than kohms but it's so low.

The pullup resistors should have no effect on the readings. Can you post pictures of your changes to the board and show us what you are measuring? How are you measuring resistance with the BME680?
