Possible if
Playing as
希腊王国
Achieved if
Formed the 
拜占庭帝国
The required states are in purple. The other colored states are required for the other decisions and are not required for the achievement.
To fulfill the Achievement I Swear I'm Not a Byzantophile, 希腊王国 must control all territory required to form the 拜占庭帝国. It the states that must be controlled are all the 希腊王国, 
土耳其, 
保加利亚 and 
南斯拉夫 states, 
阿尔巴尼亚 and the states of Southern 
罗马尼亚王国 (Banat, Oltenia, Muntenia and Dobrudja).
Strategy
As 希腊王国, boost popularity of 
法西斯主义 or 
共产主义. As soon as Greece changes ideology, justify and declare war against 保加利亚. After 保加利亚 capitulates, justify against 土耳其. Prepare against naval invasions because Turkey will have a slightly stronger navy than Greece. It may be easier to use the Bulgarian land to encircle the Turkish army. Once the bulk of the Turkish army is encircled and overrun, push through Anatolia and the Bosporus Strait.
After 土耳其 capitulates, prepare for war against Italy and the Axis. Italy will be annexing 阿尔巴尼亚 and 南斯拉夫 and will soon be going to war with 希腊王国 via their national focus. It is recommended to not join the Allies. This is in case some of the territory required falls to the Soviets. A while later, 罗马尼亚王国 will join the Axis as well. It may be beneficial if land forts are placed on the border from Albania to Romania. Wait it out until the Germans declare against the Soviets. Join the Comintern when this happens. With Soviet help, it may be easier to push against the Axis. Make the push for the required states. If the Soviets take required Romanian states, give states that are not needed and ask for control for the required states. As soon as the required states are in Greek control, click the Restore Byzantium decision.
