Short answer: no.
G Play 2023 is MediaTek MT6750T based device.
One of the minimum requirements for official GrapheneOS build (in addition to manufacturer supporting it and opening the bootloader unlocking/relocking) is a a Secure Processing Unit (element, hardware on the SoC). Mediatek SoC in question (MT6750T) does not have a hardware SPU/element and thus does not pass one of the crucial minimum requirements.
Currently it looks like that the first (and so far only) Moto phone to get the GrapheneOS support in 2027 will be a flagship Moto device in 2027, most likely running Snapdragon 8 series Soc (8 Elite Gen 6), which has hardware SPU inside.
So, everybody asking if your current Moto device will be supported officially by GrapheneOS in the future: most likely no.
