Made my analog water meter smart. Can I manually set a starting value in InfluxDB?

I set up a HomeWizard water meter with my analog water meter. I have influxDB as an add on.
The HomeWizard integration creates an entity for total water usage in m3 and current usage in liters /min.

Now I would like to have the current value of my analog meter as an offset for the total water usage.
Can I just go ahead and change the m3 value in the influx table?
When I run the query

USE “home_assistant”; SELECT * FROM “m³” WHERE (“entity_id”::tag = ‘hw_watermeter_total_water_usage’)

I get a table where „m3.value“ is increasing.
Can I just change the last value and it just keeps increasing from that value from now on?
