Is there any way to use 'or' when filtering data via rest api?

Question

Bitrix24

Good afternoon. Can you tell me if it is possible to somehow register to return leads in which one of the fields is not empty?
"!UF_CRM_1543223045"=>'',
"!UF_CRM_1543223105"=>'',
"!UF_CRM_1543223080"=>''
(now it checks that all fields are not empty)

"filter"=>array(
        ">=DATE_CREATE"=>$dateM,
        "=UF_CRM_1526286536759"=>array('cpahub','api cpahub'),
        "!UF_CRM_1543223045"=>'',
        "!UF_CRM_1543223105"=>'',
        "!UF_CRM_1543223080"=>''
    ),
