Hello Steve,

Thanks for reaching out to us.

Unfortunatelly, there is no option to hide the pricing, unless if edited with custom CSS code.

You can use this custom CSS code, for example

#amelia-container > div.am-fs__main.am-rw-768 > div > div.am-fs__main-content > div.am-fs__payments > div.am-fs__payments-price > div > div.am-fs__payments > div.am-fs__payments-service > div.am-fs__payments-services-open > div > p.am-amount{
    display: none!important;
}
#amelia-container > div.am-fs__main.am-rw-768 > div > div.am-fs__main-content > div.am-fs__payments > div.am-fs__payments-price > div > div.am-fs__payments > div.am-fs__payments-service > div.am-fs__payments-services-open > div > p:nth-child(1){
    visibility: hidden!important;
}
#amelia-container > div.am-fs__main.am-rw-768 > div > div.am-fs__main-content > div.am-fs__payments > div.am-fs__payments-price > div > div.am-fs__payments > div.am-fs__payments-service > div.am-fs__payments-services-open > div > p:nth-child(1):after{
  content:'place any text you want'; 
  visibility: visible;
  display: block;
}

Custom code needs to be applied to the page where the booking form is. Depending on what you're using (Gutenberg blocks, or some page builder), adding the CSS or JS can be done in a few different ways. 

If you need help with adding custom CSS to the page, please take a look at this article.

Let me know if it works.
