netflix for ios 10.4

No there is not.

Netflix App Requires iOS 12.0 or later

So if you can only run iOS 10, then you can't use the Netflix app on your iPad

Update support for iPad4 formally ended September 2017. The final iOS releases for this model were iOS 10.3.3 (WiFi Only models) and iOS 10.3.4 (WiFi & Cellular). iPad4 cannot be updated to any later major version of iOS as it lacks the minimum hardware requirements needed to run more recent versions.

Many App Developers have also dropped support for older devices and iOS versions preceding iOS11/12 (and in some cases, iOS/iPadOS13) - and have withdrawn older versions of their Apps from the Apple App Store. Once the Apps are withdrawn, you’ll not be able to (re)download or install them. Withdrawal of Apps supporting older models of iPad is making their utility and usefulness significantly more limited.

If Apps that you need to use now have higher minimum iOS-version requirements, your only option is to replace your iPad with newer model. Even the basic current iPad7 supports current iPadOS 13.x - and has hardware specifications that will vastly outperform your old iPad4.
