Legacy Android 4.0 CA-Certificates Update

I have two legacy Android 4.0 Garmin Monterra devices. It's not possible anymore to open the Google Play Store or some websites. When I open most of the websites with Chrome, I receive an SSL error 107. Some websites with HTTPS or HTTP are possible to open. I'm guessing that there is an issue with the CA certificates. I found this solution [Update trusted SSL root certs in AOSP](https://stackoverflow.com/q/68587205/2821954) , but it's not possible to copy the certificates to the devices. I tried the ADB-Shell but without any success (permission issue). Is there any solution to update expired certificates? Is it possible to convert the ca-certificates from the .0 file format to any other possible format and to import over the SD certificate import from Android 4.0?
