It seems there are some minimal statements that must be made in a ceremony but if you speak to a officiant directly I would imagine you can customize vows to a certain extent, such as if you do not want to seal the ceremony with a kiss.

What is the minimum requirement for a wedding ceremony?
We are asked this repeatedly, by couples who are eloping, or who just want to have a basic legal wedding ceremony, without any fuss. We’ve answered it in several places, but here is another rundown, just to be helpful.
To be legally married, you don’t need the rings, the music, the bridesmaids, you need just 5 things:
1. The Statement – of the proper names of the persons who have come to be married, so we know we have the right people. (”We are gathered here for the wedding of [name] and [name]”)
2. The Intention – ”Are you, [name] here of your own free will, and do you intend to marry [name]. This is the ”I do” that you answer individually, in front of witnesses, either 2, or 200 of them.
3. The vow: ”I [name] take you [name] to be my lawfully wedded husband/wife”. You are speaking to your intended spouse, not to the minister, and not to the witnesses, as in step. You have turned to face each other, and this is your promise to become each other’s legal partner.You may say this in your own words, and there are many variants.
4. The Signing: The officiant and the witness/es sign the license and date it (sometimes to the second, in a state where you have a waiting period). The Bride and Groom may sign as well, depending upon the license. They have already signed when they applied for the license.
5. The declaration: ”In front of these witnesses, this couple has declared their intention to join their lives in marriage..and we now accept them as husband and wife”.
