How to control domestic hot water with Nest?

Done the hard wiring, but some where I need to set hot water to come on for an hour a day, can see where to set room temperature, but not how often domestic hot water is heated.

Not had much to do with Nest, but is this any good? https://support.google.com/googlenest/answer/9259578?hl=en-GB

Found it, had to select other as boiler type on the thermostat and enable domestic hot water.
