There's no direct option for "auto scale" as of QGIS 3.38. There's definitely potential here for implementing that in a future QGIS version! One potential solution you could use in current releases would be to take advantage of the data-defined control over the minimum/maximum elevation in the layout item, so that each page in the atlas can have a different elevation range. You could either set this to a field and prepopulate each feature with manually entered min/max elevation values, or potentially use some fancy QGIS expression magic to dynamically pick a range based on other existing atlas feature fields/geometry...!
