Thank you @random-parts for help, it has brought me to the right track. If someone else will try to solve similar problem in PHP in feature, please find bellow fully working example:

    $client = $this->getClient();
    $service = new Google_Service_Sheets($client);
    $ary_values = ['yes','nope','maybe','never ever'];

    foreach( $ary_values AS $d ) {
        $cellData = new Google_Service_Sheets_ConditionValue();
        $cellData->setUserEnteredValue($d);
        $values[] = $cellData;
    }

    $conditions = new Google_Service_Sheets_BooleanCondition();
    $conditions->setType('ONE_OF_LIST');
    $conditions->setValues($values);

    $setRule= new Google_Service_Sheets_DataValidationRule();
    $setRule->setCondition($conditions);
    $setRule->setInputMessage('Please set correct value');
    $setRule->setShowCustomUi(true);

    $range = new Google_Service_Sheets_GridRange();
    $range->setStartRowIndex(1);
    $range->setEndRowIndex(5);
    $range->setStartColumnIndex(1);
    $range->setEndColumnIndex(2);
    $range->setSheetId(YOUR_SHEET_ID); //replace this by your sheet ID

    $valReq = new Google_Service_Sheets_SetDataValidationRequest();
    $valReq->setRule($setRule);
    $valReq->setRange($range);

    $sheetReq = new Google_Service_Sheets_Request();
    $sheetReq->setSetDataValidation($valReq);

    $bodyReq = new Google_Service_Sheets_BatchUpdateSpreadsheetRequest();
    $bodyReq->setRequests($sheetReq);

    $result = $service->spreadsheets->batchUpdate($fileId, $bodyReq);
