If it's not in Bluetooth->"L2CAP Options" or "ATT and GATT Options", then it's in the prj.conf file.

-edit: Found these configs in proj.conf;

CONFIG_BT_L2CAP_TX_MTU=247

CONFIG_BT_CTLR_DATA_LENGTH_MAX=251

CONFIG_BT_CTLR_PHY_2M=y

Connection parameters can be found in: kconfig/menuconfig->Bluetooth->ATT and GATT Options->Configure peripheral preferred connection parameters.

That's exactly the sample I'm running. The issue is I can't find variables in the menuconfig that correspond to those settings, and no code I can find uses the zephyr api to set them.

Parameter	Value
ATT_MTU size	247 bytes
Data length	251 bytes
Connection interval	320 units (400 ms)
PHY data rate	2 Ms/s

Could you let me know what the config variables for each of these is?
