Change value of utility meter

Configuration
1

I have some utility meter helpers which are running for years now.
They use a Riemann helper as input and this works great.
But once in a while, the Riemann sensor can be negative, but the utilitymeter helper keeps adding up and does not substract the negative value from the total.

Now I have discovered, that I had to turn on the net consumption option. But now, I can not change it anymore in the already created Utility meter.
I would like to keep the history, so I would not like to create a new utility meter.

I have found the setting in the
config.storage\core.config_entries file:
Is it possible to change the value in this file from:
“net_consumption”: false
to
“net_consumption”: true

Or will this create problems?
If this is not possible, are there other ways to change this and other values, which are not available under the cog icon of a heper/entity?

If you delete an entity, then create a new entity and give it the same entity id, it will continue to use the previous history.

Deleting an entity does not delete history.
