is there a possibility to modify autoscript_aml to do not modify env partition on NAND and just boot to libreelec?
i just wish to experiment with LE on sd, but as i see it adds boot entry to bootloader config.
Unless you have a WeTek Hub the only way to boot without adding a boot entry would be to use toothpick method every time you boot and of course a proper autoscript. You may also need to know that changes to env can be reverted any time to default values by executing defenv; saveenv over serial console or in autoscript.

2. How do I turn off the WiFi modules? I do not want to have them on, while not needed.
First check your module name using lsmod and blacklist that module.
