With your device what @MarcusMüller wrote in his answer perhaps applies. There are devices, though, which are explicitly designed for a dual-boot usage, for instance the Volla phone. Notice, though, that it uses AOSP, a de-googled Android without Google Apps and Play Services. This is good for your privacy, but perhaps bad for your gaming experience.
You could use microG and try your hand at the Aurora or F-Droid app stores, but your mileage may vary if you are used to using Google services. There is also the possibility to anonymously use the Google store.
For the Linux side of the dual-boot system there is Ubuntu Touch. It works with many (rooted) phones but notice that you need a PC to install it. In short: you install the packages adb, fastboot and ubports-installer, then connect your phone via USB to the PC and start ubports-installer.
PS: I said above that the Volla phone is dual boot. The web site says so, the developers say so and a German computer magazine (LinuxUser 04/23, p78ff) said so in an article about the Volla phone 22 and X23, but obviously @ChanganAuto (see his comment below) knows better and they are all a bunch of liars.
The mentioned article also claims that
Möchten Sie Android lieber meiden, steht Ihnen mit Ubutuntu Touch eine Linux-Variante zur Verfügung, die das Volla Phone 22 ebenfalls zum mittlerweile tauglichen Begleiter durch Ihren Tag macht.
If you want to avoid Android, there is Ubuntu Touch, a Linux-variant which makes the Volla Phone 22 a capable companion for your day.
