Have applications that use QVDs very large, and when I enter the property, even that does not make any change, all objects reload all data, and this takes a long time.
Is there a setting so that only recharge if there is a change?
No there isn't. To mitigate this you do some things to make developing more comfortable.
You could select some values in a couple of fields and the use the reduce the date in the document (File -> Reduce Data -> Keep Possible Value). When you've finished altering the document you can reload the document to load the entire data set again.
You can add FIRST 1000 above the load statements in the script to load only 1000 records in each table. Don't forget to comment out or remove those lines when you're done developing so a reload will load the entire data set. See the help file for more information on the FIRST keyword.
You can hide or minimize other charts so they won't be recalculated when you make a change. Or you can add a sheet where you do the developing on just one chart (or just a few) at a time and only move the chart to its final sheet when you've finished it.
