It depends on your definition of ‘deGoogle’. You can disable the Google apps on most Android phones. They’ll take up storage space, but won’t run.

If you’re getting a second-hand phone and want to completely deGoogle it, you can check if (1) the bootloader is unlockable and (2) custom ROMs are available online (e.g. Lineage OS compatible devices). In general, Xiaomi, Motorola and Pixel devices have unlockable bootloaders, but not all their models have custom ROMs.

Long answer: If you won’t use your system for gaming (or anything requiring third-party drivers) and trust Microsoft to not fuck up and will also encrypt your disc, then Secure Boot makes you safer. Otherwise it just causes trouble.
