When the buy buttons are not on the collection template itself and instead collection page sends them to the product page then use an alternate template with the buy-buttons turned off and use a custom-liquid section for the outbound link or to surface a metafield on each individual product that exposes a metafield.

If the buy buttons are on the collection page itself , such as add-to-cart or quick-buy buttons, then you will need an advanced customization to change the themes code.

If you need this customization service you can contact me directly.
Please provide context, examples: store url, theme name, post url(s) , or any further detail.

I have a different template for this collection and products page. 

the buy button on these specific products is hidden - I would love to use the custom-liquid section for the outbound link 

but I don't know how... 

can you help with that?

Setup a test product published to the online sales channel.

In settings create a product metafield definition(MFDF) of a url type or text.

Figure out a good name it something like marketing.external_landing_page_url  , merchandising.external_purchase_url ; those are suggestion really think through the long term name for this data.

In a custom-liqud block you'd get the output using something like {{ product.metafields.marketing.external_landing_page_url.value}} then tailor the html to need.

Note this is a static url to have dynamic it per variant selection is an advanced customization that would instead use a MFDF on variants and require creating javascript code.

Good Hunting.
