How can I show discount without decimal values?

We are using shopware 6 with jtl wawi connector
When ever we provide an product on sale it shows to our customers that 26.74 % sale but we want them to show rounded amount without decimal like 26% or 27 %
how can we do it in shopware is there any plugin who can help with this ?
or any possibility with out plugin.

Edit the template file and use twig’s round function. You need the Custom Template Plugin or a own plugin for that.

But I am trying not possible to edit template file.
is there any other possibility

Not to my knowledge.
