People on here have done it or discuss it quite a bit. Put into the search “YHWH”, “Yahweh”, “Jehovah”, or “Jesus” with one of these words “summon”, “invocation”, or “evocation”. You should get some decent info (albeit experiences will vary).
The problem with the god of the Bible is that he was either an ancient ancestral deity of the Ivrim (Hebrews) that eventually merged with or replaced another Canaanite deity that gave rise to a new god. Or he could be simply an egregore inspired by other popular deities locally.
Another problem is all the thought-forms that exist of Yahweh and Jesus. Cults, denominations, and individuals have created their god based off of their interpretation of bible, philosophy, or dogma. Over time these thought-forms have gained some degree of sentience and power because of the energy their followers have fed them. But other versions have seemingly died or are fading. Now are their actual entities that assume the deific mask of YHWH or Jesus? I believe so.
Jesus has some specific issues to consider. With him you could get, like YHWH, an egregore or an entity that has assumed the identity of JC through the deific mask. Another unlikely, but not out of the realm of possibility, option is that some have conjured his human ghost. If he was half of what the New Testament says, he might have risen to a higher state like something similar to an ascended master.
My suggestion to get to the oldest version of the god of the Bible is to summon him with the Tetragrammaton in the Canaanite script.
Incantations can be as easy as the Psalms (chapter 119 if you can stand to read that much), prayers from the Jewish tradition, or just repeat “Hallelu-Yah, Hallelu-Yah, YAAAAAAHHHHHH (vibrate) Hashem, Hashem, Adonai Elohim.” Deuteronomy 6:4 could cantilated or vibrated in Hebrew would also work. “Shema Yisrael, Yah Eloheinu, Yah echad.” Just an FYI, in modern Judaism they don’t say the Tetragrammaton. Rather they use substitutes like Hashem or Adonai in its place to protect the sacredness of the name.
If you need ideas on tools maybe print or right out by hand the Hebrew of a Torah passage. Either something about the revealing of his name or a part about his covenant with ancient Israel or Abraham. The books of Genesis and Deuteronomy would be good places to grab a passage or two from. If you have a rams horn (shofar), White and gold candles, Frankincense and Myrrh for incense, red sweet wine, bread (challah if you can make or buy it), white table cloth, a couple pomegranates, and maybe some Jewish instrumental music (look into Temani or Sephardi traditional songs). Having on all white with your head covered would also be an added touch.
Of course, none of these tools are absolutely necessary but I’m just providing some ideas on how to connect to that ancient current. Also I’m not sure if this plays a part in it but do remember YHWH and Jesus (the “Yeshua” version) have an aversion to pigs being eaten or used for “sacred” purposes. Big no, no, and is one of the reasons the Temple had to be rededicated because the Greeks desecrated the altar with sacrifices of pigs to a foreign god.
While I may have given these suggestions here I’m not endorsing the Bible, YHWH, or Jesus. I have my reasons and many times it falls into logic, rationale, and other internal problems with the theologies and the text itself.
