Yes, perhaps. Eg., for Xperia IV is SW_binaries_for_Xperia_Android_13_5.4_v2b_murray. I don’t know the differences between A 13 and 14.
It should be easy just to unlock boot loader and install SFOS without any backing of Android. I’ll keep Xperia 10 V as Android so far due to Samsung Galaxy Watch. Perhaps change to SFOS after 2-3 years, too.
