I'm trying to upgrade from Moodle 3.5 to Moodle 3.7
However, during the upgrade the plugins i am using (example: LMB, SHaring Cart) is set to be "Missing From Disk".
Is there any solution to upgrade Moodle and the plugins i am using at once?
(The update notification is turned on before the upgrade process)
No there isn't.
The best advice is to make a copy of your site and do a trial upgrade. I would do that by taking a clean copy of Moodle 3.7, adding all the appropriate plugins (correct versions) and then doing a test upgrade.

When you're happy, you can copy over you 'custom' Moodle (core 3.7 plus plugins) over to the live site.
It probably also depends on what you mean by upgrading - if you update the code base you have (e.g., using git - leaving plugins outside the core alone), or if you essentially exchange all files in your setup with the new version (thus removing the code for plugins).
