Virtuoso supports SPARQL 1.1 as can be seen from the Virtuoso Examples Collection for SPARQL 1.1 page.

SPARQL 1.1 IF function example using BIND:

SELECT *
WHERE
        {
             VALUES ?s4 { 'US' 'United Kingdom' } 
             BIND (
                    IF (?s4 != 'US',
                            IRI(CONCAT('https://91-divoc.com/pages/covid-visualization/?chart=countries&highlight=',encode_for_uri(?s4),'&show=50&trendline=default&y=fixed&scale=log&data=cases#countries')), 
                            IRI(CONCAT('https://91-divoc.com/pages/covid-visualization/?chart=countries&highlight=',encode_for_uri(bif:INITCAP(LCASE(?s4))),'&show=50&trendline=default&y=fixed&scale=log&data=cases#countries')) 
                    ) as ?divocCountryURL
                  )
