Is there an easy I could try your target in equaliser apo?

I don't know about "easy." You could try EQ'ing whatever you currently have by ear but that takes a lot of experience and practice. It helps to have a "711" coupler to make measurements. REW helps with modeling. I've EQ'd the $10 Panasonic RP-HJE125 to it for the most part. I've EQ'd the Soundcore Sport X10 to being pretty close. EQing 3KHz+ must be done by ear since it is not accurately measured by coupler and is anatomy and insertion depth dependent. Might take you 20+ bands but it CAN be done.

"Flat" by measurement is not the same as "flat" by ear since human hearing is not linear.

If you want to EQ by ear and want a "flat" sound, basically what you want is equal loudness from 10Hz to 20KHz. IEMs are more capable of this than headphones in regards to distortion.

If you want a "flat" sound by measurement (dB SPL) (but doing it by ear) then there should be a gradual roll-off from 1KHz down to 10Hz, a -3dB dip around 1.5KHz, a rise to +3dB at 3.2KHz, then a gradual roll-off up to 20KHz.

I think a happy medium is somewhere in between. Most people like a bass boost and treble is subjective too. Listening level matters. Having a smooth response is key so no stabbing peaks or troughs.
