How to reduce the gap between safe left and right sides?

How to reduce those gaps:

These gaps are automatically getting applied between cols, inputs and etc…
This is very good behaviour of the framework, how ever I need to adjust the gap so it will be closer, but I didn’t find where to do that.

I am using React with F7 v5.
Thanks…

If you are using Grid, then it configurable with --f7-grid-gap: 16px; CSS var https://framework7.io/docs/grid.html#css-variables
