It works the way I want but there's a warning: React Hook useEffect has a missing dependency: 'yxz'. Either include it or remove the dependency array

Question

I'm new to React and need some help.

I came across the concept of useEffect so I started to implement it in my small webapp. I want to calculate the price according a changing value in my formData object. If formData.koerper changes it triggers first the setFormData function and then updateK which I further use to trigger useEffect. setFormData and updateK are inside the handleKoerper function. The code is as following:

import React, { useState, useEffect, useRef } from 'react'
import { Form } from 'react-bootstrap'
import './Forms.css'

function PictureCustomization({ formData, setFormData }) {

    const settingPrice = () => {
        if (formData.koerper === "Ganzkörper")  {
            let calc = formData.preis + 10
            setFormData({...formData, preis: calc})
        } else {
            let calc = formData.preis - 10
            setFormData({...formData, preis: calc})
        }
    }
    
    const [updatedK, setUpdatedK] = useState(0)

    const isFirstRun = useRef(true)

    const handleKoerper = (event) => {
        setFormData({...formData, koerper: event.target.value})
        let newUpdate = updatedK + 1
        setUpdatedK(newUpdate)
        console.log(newUpdate)
    }

    const handleHandgemalt = (event) => {
        if (event.target.checked){
            setFormData({ ...formData, handgemalt: event.target.checked })
        } else {
            setFormData({ ...formData, handgemalt: event.target.checked, format: 'Digital' })
        }

    }

    useEffect( () => {
        if (isFirstRun.current) {
            isFirstRun.current = false;
        } else {
            settingPrice()
        }
        // eslint-disable-next-line react-hooks/exhaustive-deps
    }, [updatedK])

    return (
        <div>
            <div className="form-title">Bild Personalisieren</div>

                <Form.Group controlId='formKoerper'>

export default PictureCustomization

If I don't include // eslint-disable-next-line react-hooks/exhaustive-deps in my useEffect there will be a warning message which tells me to include settingPrice in my dependencies. If I include settingPrice in my dependencies, useEffect will start an infinite loop which makes sense to me since I'm triggering settingPrice over and over again. So, my question is: Is there something I can change to not bypass the eslint rule? Bypassing the rule just feels wrong to me.

Also, I know I could put setFormData in my useEffect and therefore not use a seperate function but that would lead me to the same problem anyway.
